Yeah, I'm curious how it works out as well.
I'm not longer willing to regularly give up sleep. For me, it's more important than just about anything I would replace it with.
So, if I wanted to add 30 minutes of exercise into my day, I would have to subtract 30 mins of something else and there just aren't many things that I want to give up anymore.
I wish I could afford to be retired. I could retire and easily replace my working hours with making things and learning things and writing and reading and playing music, watching movies and travel and other hobbies. Maybe I'll buy a lottery ticket on the way home from work.
