If you think you can do it, you can.
If you're going through hell, keep going.
You never know what motivates you.
Be kind whenever possible. It is always possible.
The secret of getting ahead is getting started.
Know or listen to those who know.
I can, therefore I am.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Moderation is the inseparable companion of wisdom, but with it genius has not even a nodding acquaintance.
Doubt is the vestibule through which all must pass before they can enter into the temple of wisdom.
