There is a saying in personal finance:
You are the boss of your budget until you are done with it and then it becomes the boss of you.
Same thing with your business.
So building a budget or a business, build wisely so later you have a good boss.
Do what you love so that when it captures you, you are captured by something you truly love.
I have learned that when you pursue what you are passionate about, whatever it is, it has the potential to change you.
