My parents grew up poor, but I retired early at age 28 with $2 million - here are the 6 best pieces of advice I can give you about making money

Average habits lead to average outcomes — if you want an above average net worth, you need to make above average efforts.

The median retirement age in the US is 63. The median net worth of households aged 65 to 69 is $193,000. Between that and the average social security, that means the average retired couple has to live on less than $2,000 a month.

If that doesn't sound appealing to you, then you'll have to do better than average.

While it sounds obvious, this is actually a game-changing thought. In order to retire early and enjoy atypical wealth, you will be employing strategies that most of your friends probably don't use. You will be investing your money differently. You will be living differently. And that's okay. It's to be expected.

Information is the key to riches.

While a certain amount of effort and discipline is required to amass wealth, the biggest distinguishing factor is knowing where to apply that effort. What we pursue is limited by our knowledge of what's out there. The difference between two individuals with the same circumstances but different knowledge of their opportunities can easily be a million dollars. A few examples:

• I discovered that graduating college in three years instead of the usual four could completely pay for retirement. Between the cost of a year's worth of tuition and the value of one year's worth of income, the swing in my net worth was over $1 million if I set it aside and let it grow until I was 55. In other words, knowing about and employing that one strategy could pay for my entire retirement.
• I just had my first child and have started thinking about how I can set him up for success. Did you know that the average family can make their child a millionaire? The strategy doesn't even require them to find more money in their budget, just to deploy it differently.
• Americans have $4.2 trillion in actively managed equity mutual funds, which could probably be deployed differently for better returns. According to Dow Jones S&P Indices' Scorecard, passively managed index funds outperformed 82% of their actively managed peers over the 15-year time period. Not only that, but the fees charged for a passive fund are significantly lower.

Between fees and superior performance, it's very likely that moving your investments from one to the other could improve your returns by at least 2%. Did you realize if you invested a $200,000 portfolio in low cost index funds rather than high fee mutual funds, historical performance would suggest you would make $600,000 over the course of 20 years? No additional work for you — just an hour or two to research and make the decision. That's $600,000 of lifetime value for two hours' work.

The right small effort, applied today, can yield six figures in the future.

So how do you ensure you're in the know about the best opportunities? We have never lived in a better age for this. The advent of technology allows us to reach well beyond our normal circles and get exposure to the best, most impactful ideas globally. You can build a system to regularly show you the best ideas, and let those ideas stack on top of one another to grow your wealth for you.

Career skills and career management skills aren't the same thing — having both will earn you thousands more.

Earning an extra $20,000, $30,000, or $100,000 a year is more achievable than you think.

Career management — figuring out how to position and improve yourself for the fastest promotions and highest compensation — requires a set of skills very few people invest in. All the talk is about the technical skills required to perform one's job. Obviously you need to be competent in your role, but the skills that make you a good accountant are not necessarily the skills that will help you land a great job as an accountant or get the highest raise once you are an accountant.

An accountant has to have good knowledge of the tax code. She has to be detail-oriented and independent. The additional skills necessary to land a role as an accountant are emotional intelligence, initiative, networking, and negotiation. And these are completely different.

The job I held was a highly competitive one. Before my first interview, I reached out through friends of friends to try and find someone who was already in the industry who would spent 15 minutes talking on the phone with me.

After I did this, I cold-emailed someone at the firm I was interviewing with to do the same thing, hoping that I could get a little background on their specific style and tailor my approach. Turned out the gentleman I spoke with ended up being one of my interviewers, and he told me after I got the job that he'd spoken highly of my initiative in contacting him to prepare.

I also learned a lot during my career about what levers influenced compensation the most. Things like knowing what to look for in an employer and how many years you want to stay at each company for maximum income are factors which will help you achieve 30%+ annual pay increases.

You can earn as much outside of work as you do at your full-time job.

We live in a technological age. The opportunities to build a side hustle have never been better than they are now. Not only will they kick in extra income, but if you build a successful side business, it can easily become your main source of income with the added flexibility of working from anywhere around the world.

I came to this one later than I would have liked: It was only after I retired that I realized I had underestimated the possibility of income during retirement and thus worked more years than I needed to because of it.

After I retired, I started a blog about personal finance. It was meant to be a hobby — it's a subject I love. It became a passive income stream sort of by accident. In its first full year it made $62,326 with only five hours of writing a week.

I happen to think that blogging would be a viable, lucrative side hustle for many folks. For one thing, the start-up cost is small, maybe $30 to $40 for hosting per year. And it's an extremely horizontal business model — almost any subject can eventually become a profitable blog. There's a fitness blog that makes the couple who own it $145,000 a year. A blog focused on entrepreneurs that makes $3 million a year. A blog about food recipes that makes $1 million a year. You'll find breakdowns of how much bloggers can make over here.

If blogging isn't your style, there are a million other options you can pursue. Perhaps you can submit your photographs on a stock photo marketplace like iStock. You can host dogs in your home for $20 to $50 a night through Rover. Maybe you're an accountant who wants to teach small business owners the basics of managing their books through paid courses on Udemy.

While some side hustles are more lucrative than others, there will certainly be at least one option that fits your skill set and interests that could make you $20,000 to more than $50,000 per year in your off hours.

Earning more requires its own set of skills. If you spend even a little time thinking in this mindset, you will vastly outrun the average guy, who spends zero time on these skills, and you will be compensated handsomely for it.

Money begets money.

The difference between having no money and even a little money is staggering. I remember reading an article about why those in poverty find it hard to save. One example the article used was about how someone might go to the store and not be able to afford buying in bulk. Certainly they can see that buying one roll of toilet paper is more expensive per unit than buying the 24-pack, but they don't have the extra $10 to "invest."

This is a small example most people understand, but the principle applies at nearly every incremental increase in wealth.

• If you're not scrambling to get your bills paid, you might be able to consider taking on a side hustle for five hours a week. That side hustle might blossom into a six-figure paying business that allows you to travel the world while working only four hours a week.
• If you have $50,000 tucked away in savings, perhaps you can afford the down payment on a home so you can buy and build equity with your monthly payments rather than giving it all away in rent.
• If you have $100,000 or $200,000, many banks and brokerage companies will offer you special incentives like lower trade costs and higher sign-up bonuses worth thousands of dollars.
• If you have a million dollars, you are considered an accredited investor. You can invest in private placement opportunities. You can be an angel investor in a startup and back commercial real estate development projects. Your assets qualify you for a larger mortgage, which allows you to buy multi-family properties, which generally show higher returns than single-family rental homes.

In short, more money means more options open up to you. Better options. The more money you have means you accelerate faster and faster towards massive wealth. Money begets money, so it's worth the hard work and sacrifice to build that first small nest egg.

One of the most recent examples of this in my own life is using my accumulated wealth to get a discount on my mortgage interest rate. When we bought our home, I spoke with the private client arms of some of the major banks. A common benefit of being a private client is a discount on your mortgages. All I had to do was transfer a chunk of my buy-and-hold stocks into an account stewarded by them in order to qualify.

What's more, there was no time limit as to how long I had to hold my assets with the private arm. Simply having these accumulated assets got me a discount that was worth $300,000 over the life of the loan. Those same accumulated assets allow me to regularly take advantage of brokerage sign-up bonuses. By moving my money twice a year, I make $4,000 for two hours of work.

Do everything you can to accumulate that first $10,000, $20,000, or $100,000. It will create a snowball that speeds you towards wealth far faster than you can imagine.

Kickstart your journey to wealth by tracking your net worth.

Say you're interested in accelerating your financial progress and overwhelmed with all the possibilities you can pursue. What's the single best thing you can do for yourself in the next five minutes? What can you do right now?

Simple. Start regularly tracking your income, expenses, and net worth.

If you think about every engaging thing you've done, they probably had some way to measure your progress. How many goals you scored. How quickly you can complete a set of problems.

Personal finance is no different. You improve what you measure.

You need to be able to track your income, expenses, and net worth. It needs to be staring you in the face every day. Once you start seeing these key metrics improving regularly, it will spur you to dig into the details and find opportunities to grow it faster.

I use Personal Capital to track all of my finances. Their dashboard is free, accessible to you anywhere, and it hooks up to all your different accounts to give you a single pane of glass from which to view your financial life. It also imports as many months of data as your credit cards and bank statements allow, which will enable you to immediately dig in to spot trends in your past behavior and opportunities to improve. But even a good old spreadsheet would be a vast improvement.

If you do nothing else today, start tracking your key metrics of income, expenses, and net worth. It will show you where the opportunities lie to improve your financial picture. It is the cornerstone habit that helps build momentum for all the other things you do to grow your wealth. And every new strategy you collect on the way will be reflected in your dashboard's progress charts.

Do these things and you will find that you, too, can retire decades earlier than your peers.
