The unexamined life is not worth living.

Socrates

One should count each day a separate life.

Seneca

It is not what we get. But who we become, what we contribute that gives meaning to our lives.

Anthony Robbins

There are two tragedies in life. One is not to get your heart's desire. The other is to get it.

George Bernard Shaw

The most glorious moments in your life are not the so-called days of success, but rather those days when out of dejection and despair you feel rise in you a challenge to life, and the promise of future accomplishment.

Gustave Flauber
