Know or listen to those who know.

If you're going through hell, keep going.

The secret of getting ahead is getting started.

Quality is not an act, it is a habit.

It's always too early to quit.

Problems are not stop signs, they are guidelines.

Do not weep do not wax indignant. Understand.

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.
