I've tried doing that. Even if it is possible, I really don't like it. When married to a fixed schedule, life just isn't as much fun for me.

Have you considered a polyphasic sleep schedule? If you truly do have a non-standard circadian rhythm, you should be able to adapt one of the dual core schedules towards it.

Maybe? I was thinking more that stuff comes up that affects my schedule, and I don't be forced into living with the constraints of a 10 p.m. bedtime (or whatever time I set). More to the point, I am more disciplined about getting to bed before 12 a.m. I do not want to go bed at a fixed time.

I think it can make one feel trapped. Trapped to a schedule.

But you have to think of it as something that you choose, i.e. your own limitation, not some external limitation.

Having a normal circadian rhythm makes the rest of life a lot more enjoyable (fun) than not. Especially after 30.
