15 money lies you should stop telling yourself by age 30

You'll always be allowed a few life mulligans, but by the time you've hit the big 3-0, you should have sorted out most of the reckless habits we tend to fall into as young 20-somethings.

This is especially true for money matters, considering you're close to entering - and need to prepare for - your peak earning years.

While most of us have a general idea of what it takes to succeed, we sometimes let ourselves - and a few money lies - get in the way.

Don't let these 15 lies hold you back.
