It's always too early to quit.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

If you've got a talent, protect it.

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

If you're going through hell, keep going.

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

Expect problems and eat them for breakfast.

The dog that trots about finds a bone.
