Milln, you gotta calm down.
Don't damn yourself to a cage you put yourself in. Everyone has played terrible, it doesn't mean they ARE terrible.
Don't let your expectations of yourself get you down for too long.
Don't give yourself an out by saying you'll always be mid level, if artists did that we wouldn't have great artists. Don't worry so much about the quality of what you do and have some fun, like you do with Yosuke, the power will come in time as long as you worry more about just enjoying what you do, and keep at it without getting burned out on it.
