Getting the articulations of the fingers right intimidated me to the point of avoiding drawing people completely.
In 4th grade I had an assignment which involved drawing an image of a woman on a piece of poster board. My dad offered to help me out by showing me how to create a picture of a lady with her hands behind her back.
I was blown away to realized I could work around what seemed like an unconquerable challenge simply by creating a composition what didn't require showing the subjects hands.
This experience helped me to realize a deeper understanding of the problem solving aspect of creating art. Years later one of my favorite parts of my creative process is the time I spend thinking about how to use the space I have to express what I need to clearly. Sometimes my intention is to push myself past my perceived limitation (I now totally enjoy painting hands) or simply to figure out a way to work around what I feel like I cannot do by twisting what is within my comfort zone in a new way.
