I spent 8 years trying to be a professional musician, running my own music project. I gave up opportunities, travel, etc. for it. Lived with family a lot of those years to save money for the studio, and to work part time so I could write songs and make demos. I made some things I'm really proud of. But it didn't pick up, I didn't get signed, I made no money from it and lost many thousands of dollars from it, etc.

By the end I was completely burned out, and saw I gave up most of my 20s for that. If I were to go back I wouldn't change anything. I gave it my best shot. But like OP here, I am burned out and need to just enjoy life now.
