2. Get to know your colleagues
A cohesive team will make it much easier for you to withstand turmoil in the workplace. If your New Year's resolution is to sell more, or be more productive, try first building a team atmosphere. It will make it easier to achieve your goal when others are rooting for you.
3. Change your physical environment at work
If you are working too many hours, or feel like your work is slowly wearing your body down, find ways to make the work environment healthier for your mental and physical wellbeing. If standing desks aren't your thing, then at the very least commit to taking more frequent short breaks or use your lunch time to get away from your desk and sit under a tree. There is plenty of research that shows our productivity improves when our workplace makes us feel better.
4. Retrain or increase your credentials
Look for the financial and human resources you need this year to keep growing. You're more likely to successfully improve your job prospects when you ask others to support you while you build your skills. Can your partner help? Are there government subsidies? Even downsizing your home for a time is likely to make it easier to realize a promise you make to yourself.
5. Put aside some money for a Plan B
The best New Year's resolutions are those that are well resourced. If you can't achieve everything you want to achieve this year, at least build a little hidden capital so that you can make a bigger, more successful change next year.
