I wish I had more time, or rather the "right kind of time" to to make music in, but then again hobbies don't have deadlines - I'm not obligated to deliver anything to anyone within a specific time frame. I'd probably go nuts if I was a professional musician and had labels breathing down my neck, demanding I'd make something for them to sell. I can easily understand why a lot of big musicians fall into some kind of substance abuse.
Though, I would be lying if I said I'm not just a little jealous of them.
