Fear of failure? I don't know. But sometimes I sit and think about drawing all day and never get around to doing it. It used to be casual for me, never worried about finishing something, just sketching and doodling. But now I feel like if i'm going to sit and draw it needs to be for a reason, so i put it off. Stupid I know, but just bought a couple different sized sketchbooks to spite my anxiety. Gotta get back to basics and start enjoying my love, my passion, my mind....my art!!
