It's always too early to quit.

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

Leap, and the net will appear.

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

Do not weep do not wax indignant. Understand.

If you think you can do it, you can.

Know or listen to those who know.

Go for it now. The future is promised to no one.

Always desire to learn something useful.
