To know oneself, one should assert oneself.

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

It's always too early to quit.

The dog that trots about finds a bone.

Know or listen to those who know.

Either you run the day or the day runs you.

Never complain and never explain.

The secret of getting ahead is getting started.

Do not weep do not wax indignant. Understand.
