Yep, one: Do what you love. One day people will realize the value of what you do and everything will flow as you wanted.

A big trigger for my career change was when I read Rework from DHH. I realized that you can start small and build a product fit for a specific market - some users will outgrow your product and that's okay. As for me, I build a product I needed without really thinking if there was a product/market fit, it eventually happened.
