Angst...and a sharpie

What if I'm just drawing the same thing over and over a million times
 for the last forty years????

I was wondering to myself "Why, oh why am I keeping all those old sketch books?" The initial rationale centered around ideation. Maybe something would come in handy. Maybe I could study the evolution of style and technique. Then this thought...."All this stuff kind of looks alike. Maybe I'm just drawing the same thing over and over ad infinitum." Yes, sometimes I include Latin phrases in my internal monologue to make myself feel smart.

So I'm considering two things...One: ditch the sketch books that are only collecting dust and taking up space. Two: learn (somehow or tuther) to draw other stuff too.
