Sometimes I do pull the 16-hours-straight thing, but more generally, I can't physically handle it. For me the challenge has been knowing when to quit... getting a good night's sleep instead of staying up to finish a project, that kind of thing. Cos if I stay up to finish something I usually just end up getting too sick to go to class, which puts me behind again.

I think a major thing is that I really need to have a clean house before school starts each semester... so that major cleaning projects don't distract me. Another is that I probably should not take night classes and day classes mixed... just days. The third is that I probably should spend less time online. ;)
