You are a professional at doing it, because the stakes are high.
It’s not your hobby. Because you certainly can make money from your hobby, if you like. Your livelihood doesn’t depend on it; your quality of life — financial and/or mental — won’t change much if you don’t carry on with it.
It’s not private. Hobby is private.
Being professional means having a standard. It means you voluntarily put your work in front of others and say “this is my work. I have a standard.
I am on a professional level.
I have a principle.
I do what I like. This is what I like to do. But I also do it for others. And get recognised for it. And most of times, I get paid for it.
I don’t do it just for fun.
It’s not necessarily my profession.
But I’m a professional at it. I do my work when I don’t want to. Because I’m doing it also for others.
Because others need my work.
The stakes are high.”
