My binge and purge cycle with drawing:

Step 1: Compile lots of reference photos. I really want to be prepared, so I don't quit half-way through the project.
Step 2: Begin to draw the different anatomical features. I take great care trying to get the pose just right, to make my vision perfect.
Step 3: Get frustrated half-way through. Maybe it's because of the hair doesn't look right, or because the torso looks to fat. Or maybe even I get to the coloring phase, and realize the line art is terrible. Either way, the picture gets discarded never to be completed.
Step 4: Wait 2-3 months, where I don't draw as I realize I'm a terrible artist.
Step 5: I start to feel bad about not drawing. The nagging guilt forces me to draw something I can: an inanimate object.
Step 6: Rinse and repeat.

Proof of this: This picture.

I made the background black in the last three seconds, and it looks ten times better for it. The glow now looks really stupid though...Oh well. Yay apathy!
