During my entire life as an artist I have always sketched in pencil first and then inked. Recently I simply cannot draw in this way whatsoever. I try to force myself to do it, but it doesn’t work. Every attempt of mine in doing it ends with me throwing away the paper because the sketch is below my low standards. However every time that I pick up my sketchbook and a ball point pen I happen to make decent sketches in perspective with minimal to none construction lines. Is the issue here the size of the drawing? The medium? I can’t understand why I simply can’t draw the way I always used to.

Drawing makes me frustrated, but not drawing is even worst. I don’t get it.
