Constant work so it is important you do what you love it no longer feels like a "job" and instead is just a way of life for you that you enjoy doing and reap the rewards from. It does take a whole new mind set though and most of schooling drills it in your head do a test, get a piece of paper get a job. I don't know about you but when I did this for a few years I felt totally stuck and hated it!

With that being said since you are doing what you love instead of the other alternative yes your going to work long hard hours (maybe not always but at first) however it is going to be rewarding and fill you with great joy.
