On the human chessboard, all moves are possible. Do whatever you do intensely. Other people's interruptions of your work are relatively insignificant compared with the countless times you interrupt yourself. If your ship doesn't come in, swim out to it. The basic success orientation is having an optimistic attitude.
Sedentary people are apt to have sluggish minds.
A sluggish mind is apt to be reflected in flabbiness of body and in a dullness of expression that invites no interest and gets none. That is what learning is. You suddenly understand something you've understood all your life, but in a new way. You can judge a person's character by the way they treat people who can do absolutely nothing for them. As you live, believe in life.
