Learn to draw

I have like zero experience with drawing. But I have about 7 hours of lecture which is disposable time for me cause I would be sleeping, I think I could utilize that time to learn to draw. please help

I have been drawing gestures for years and never really settled on a "best map" for the body. Anyone have examples for how they like to draw the body?

EDIT: if you are reading this get the morpho books. It's an amazing resource.
