If you're going through hell, keep going.

Never complain and never explain.

By failing to prepare, you are preparing to fail.

If you've got a talent, protect it.

Do not weep do not wax indignant. Understand.

The secret of getting ahead is getting started.

To know oneself, one should assert oneself.

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

Know or listen to those who know.
