When you do something praiseworthy, you will get approval.
The feedback you get is going to make you feel good, and possibly you will set out to do some other things that will be worth the praise of your peers and audience.
Are you in it for the doing or for the approval?
That is a silly question to ask, because most likely you have mixed motives.
The question to ask, instead, is: would you do it anyway if there was no approval?
That’s how you define passion.
