Start small and prospect where you have a reasonable chance of success.Along the way you'll learn and build a customer base. Later, you can leverage that customer base -- and everything you've learned -- to successfully hunt bigger game.

Dream Big, But Focus Small

When choosing your side hustle, pick something you want to do, be or achieve, and actively work toward it. Not only will you enjoy the sense of accomplishment that comes with progressing toward a goal but you'll also feel better about yourself and your life.See your side hustle time as "me time." Because it is -- it's time you spend making the most of your life.

Only Spend Money On Actual Efficiency

To avoid having to work for years before turning a profit, start a side hustle you can fund through savings or that you don't need to fund.
