If you are like me, you are extra hard on yourself and your art. You are your own worst critic and often you're overly critical nature of how you are doing something hinders instead of helps you grow. I think this is due to a number of reasons but the graph below explains exactly why I am so hard on myself.
Looking back on where you came from and seeing that improvement is one of the best ways to shut that stupid critic in your head up. It works for me at least.
