Quote

Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in

Without music, life would be a mistake

Virtue is a state of war, and to live in it we have always to combat with ourselves

We make war that we may live in peace

We should employ our passions in the service of life, not spend life in the service of our passions.

Don't take life too seriously; you'll never get out of it alive
