Business or pleasure?

If you do what you love, you'll never work a day in your life! 


A hobby becomes a profession when you have to do it. If you're tired or stressed from a hobby, you take a break. But once that hobby becomes a profession, you have deadlines and you can't avoid the parts that you don't like as much. 

This doesn't mean you shouldn't "do what you love," but be careful about making a hobby a profession, lot's of changes happen when you go from 5 casual hours a week to 40-50+ required hours per week.
