The key is to keep company only with people who uplift you, whose presence calls forth your best.
Epictetus

The individual has always had to struggle to keep from being overwhelmed by the tribe. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself.
Friedrich Nietzsche

In dwelling, live close to the ground. In thinking, keep to the simple. In conflict, be fair and generous. In governing, don't try to control. In work, do what you enjoy. In family life, be completely present.
Lao Tzu

Remember when life's path is steep to keep your mind even.
Horace

Always do sober what you said you'd do drunk. That will teach you to keep your mouth shut.
Ernest Hemingway
