Fear doesn't exist anywhere except in the mind.

People aren't interested in you. They're interested in themselves

If you can't sleep, then get up and do something instead of lying there worrying. It's the worry that gets you, not the lack of sleep.

By all means take thought for the tomorrow, yes, careful thought and planning and preparation. But have no anxiety.

No matter what happens, always be yourself.

In short, we lose the freshness and spontaneity of true conversation. These are areas in which everyone interested in self-improvement will seek to improve.

Each party should gain from the negotiation.
