Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

It's always too early to quit.

The dog that trots about finds a bone.

Be thine own palace, or the world's thy jail.

I can, therefore I am.

The wise does at once what the fool does at last.

By failing to prepare, you are preparing to fail.

Leap, and the net will appear.
