It has to be you. Even if it might sound ridiculous, it’s one of the most important things. A lot of people do things they don’t like, hate their jobs, stay in dysfunctional relationships, don’t like the way they look.
It’s hard to make someone else like you when you don’t like yourself. If you are not satisfied with your work, if you don’t find it emotionally rewarding, then other won’t either.
Anything you do, you must be proud of it, it has to make you happy and you have to be enthusiastic about showing it to others. This is how fans act and that’s how your relationship with your art should be.
In order to become your number one fan you have to start doing the things you love.
