[T]he human individual lives usually within his limits; he possesses powers of various sorts which he habitually fails to use. He energises below his maximum, and he behaves below his optimum.*
William James

You are strong, self-sufficient, you make time for reading, thinking, quiet contemplation, meditation, or prayer. This need not cost a penny.**
