What do you do that you absolutely love so much that it's not working at all?
In reality, even things you loving doing become work when you make a serious career out of it. But yes, it beats working at shitty job you hate.
I work in a corp as well, but I also love photography and actually made some money doing it on a side.
People keep telling me, "Why don't you pursue your wedding photography?". Fuck no, not in a million years. I love doing photography, but it becomes high pressure work.
I think people who TRULY love their work that it never feels like they're working has to be from entertainment. Man, I'd love to be a rock star.
