If you think you can do it, you can.
Well done is better than well said.
Be kind whenever possible. It is always possible.
Who seeks shall find.
The dog that trots about finds a bone.
Know or listen to those who know.
I can, therefore I am.
Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
Responsibility for learning belongs to the student, regardless of age.
