My full-time job is actually a night job, i work 5 pm-2 am Sun-Thurs. I practice in a back room during my lunch hour and rarely get interrupted.
I also teach 1/4 time at a university, and part time at another university. Its not as bad as it seems; I enjoy teaching, and wouldnt be able to do it if i had bankers' hours. It also allows me to be at home during the day to take care of my 2 small kids. They like my playing, and I don't have to ship them off to day care, unless its a teaching day.
If I'm careful, I can fit in another hour + of practice during the day at home. On my teaching days, I can play during office hours, of course.
Sometimes I don't sleep much, but theoretically, i can get 4-5 hrs sleep per night, and another 1-2 hour nap in the afternoon.
This will change in 2 years when my youngest starts school.
The biggest problem is that I don't see my wife that often. (But maybe we appreciate each other more when we do see each other...!) I'm also not able to perform much (performances are usually in the evening) but I can still practice and compose.
