Never complain and never explain.

The dog that trots about finds a bone.

Do not weep do not wax indignant. Understand.

Know or listen to those who know.

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

The most effective way to do it, is to do it.

You never know what motivates you.

By failing to prepare, you are preparing to fail.

If you're going through hell, keep going.
