Boards, don't hit back. ~Bruce Lee

Do not practice finely skilled movements after you are tired, for you will begin to substitute gross motions for finer ones and generalized efforts for specific ones. Remember, wrong movements tend to supervene and the athlete's progress is set back. Thus, the athlete practices fine skills only while he is fresh. When he becomes fatigued, he shifts to tasks employing gross movements designed principally to develop endurance.

Loneliness is an opportunity to find yourself. In solitude, you are least alone.
