This is a drawing I will always remember and cherish. This was my first step (you will see it become a common theme) where I combined symbolism and simple characters to explain lessons or ideology.

What this one is depicting is that many times you can find solutions to your issues by examining your inner self. In this image the protagonist is being reminded by his inner shadow (something we all tend to reject) that what he seeks (the last puzzle piece) is within him.
I have found throughout my life that most of my struggles and suffering, or obstacles and challenges can be overcome by introspection and self analysis.
