It's always too early to quit.

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

Things do not happen. Things are made to happen.

Either you run the day or the day runs you.

By failing to prepare, you are preparing to fail.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

Only the educated are free.

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