Never debate or argue, but let the one goal be to keep calm, self-possessed, and cool.

Never debate or argue, but let the one goal be to keep calm, self-possessed, and cool. Do not strive to control others. You have enough to worry about controlling yourself. One of the biggest evils of this life comes from the desire to rule others. The rights you claim, grant freely to others. No one poor, weak piece of human clay has the right to dictate the road to immortality or sit in judgement on a fellow-being.
