No one ever says a 100+ and I still suck. Because repeated practice almost always yields improvement.
I sometimes reply back with, if you drew an apple 100 times. Don't you think the 100th apple is going to be significantly better than the first apple? Hell yea it is, the human body adapts quickly, we become lazy in regards applying effort. by the 50th apple you'll be throwing down lines and value so quick, it'll be scary. Your body and mind react to situations (the drawing of the apple) and problem solves through it. The brain is smart, the brain recognizes patterns and responds. It becomes automatic.
Repetition in the end is the greatest way to improve. As in art, practice should be scheduled for optimal performance increase. Think of yourself as a professional athlete.
