It's always too early to quit.

Do not weep do not wax indignant. Understand.

Things do not happen. Things are made to happen.

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

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

Only the educated are free.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.
