Men should pledge themselves to nothing; for reflection makes a liar of their resolution.

Reflection makes men cowards.

Ignorant men don't know what good they hold in their hands until they've flung it away

There is no greater evil for men than the constraint of fortune.

Ignorant men don't know what good they hold in their hands until they've flung it away.
