I've read if you do a job you love, you'll never work a day in your life. But I've also read if you work in the hobby you love, you'll regret it & it will ruin your hobby...& maybe finances too...
Both true. A lot of it is how you approach it, and perhaps even more importantly, who you work with.
The wonderful thing about hobbies if we generally do them how we want, when we want. If I don't like how a fish tank is working out? No problem, I just tear it down and start over. If I compose a piece and I'm not pleased with it, I either fix it or just discard it and make another one. If I make a bow I don't like, I give it away or use it as firewood. No big deal.
But once money and other humans get involved, one's options become more limited by other people's expectations, requirements, and personality/character quirks. Sometimes that is very motivating, and that motivation can actually be enjoyable. For example, I genuinely like my dentist and her staff, and I often take better care of her fish tank than I do of my own.
This is definitely true of making music. The "pressure" of working with other people is generally part of the fun; it motivates one to push oneself, practice hard, and get better. (Getting paid to play music is pretty cool too)
That's all true unless one is working with people one doesn't enjoy. If bosses, coworkers, or band mates are negative, pressuring, or unreliable? Then it's no fun at all.
