The happiness of a man in this life does not consist in the absence but in the mastery of his passions.

If you invest nothing, the reward is worth little

An unexamined life is not worth living.

A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success

Survival can be summed up in three words – never give up. That's the heart of it really.

Either you run the day or the day runs you.

What matters most right now, is what you do next.
