The goal is not be be prefect - the goal is to be better. Perfection is not realist or reasonable to expect. 100% is not the standard to obtain (99.9% is acceptable). As a person we have the capacity to be better. Lessons are able to be learned from past experiences thought reflection that allow one to become better the next time. Are you learning to be better? That is a question to ask each and every day. Learning has to be applied. Knowledge without application is just knowledge. Knowledge with application through experience leads to wisdom. Learn to be 1% better each day.
