Productivity, thou art my master

I'm the kind of person who likes to keep busy. I always have a few big projects and a few little projects I'm working on at the same time. I am only a little bit obsessed with productivity. About two weeks ago, I finally reached a point where I can say I am over-committed. But it wasn't until this morning that I paused to realize all the things I am actually working on at the same time (and break down how many hours per week I spend on them)...

1) I am developing a website (2-6)
2) I am continuing my oral history project (1 every other week)
3) I am editing and soliciting content for a history exhibit for this winter (2-3)
4) I am coordinating a college orientation trip for next semester (1-2)
5) I have been applying for internships and related grants (3-5)
6) I am co-teaching a photography class at a local community organization (4-6)
7) I am publishing a book (for money) (9-13)
8) I am coordinating a small-scale literacy initiative (4-6)
9) I am part of a core group of people organizing a divestment campaign on my campus (2-3)
10) I am trying to fix my health issues (which includes weekly doctor or naturopath appts) (2-3)
11) I am trying to write an undergrad thesis (included below)
12) I am posting more regularly on my blog (2-3)

That folks means 32-50 hours on top of being a more than full time student.

For the 19 credits I am taking, I have 10 hours per week in class and am supposed to do 47 hours of work outside of class.

How is this possible? I get academic credit for a couple fo the projects (like the wbepage and the photography class), I get paid for others, I colorize drawings while I wait for my doctor, I e-mail interviewees during class, and I haven't made the progress I need to on my thesis.
