Never complain and never explain.
Always desire to learn something useful.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
To see what is right and not to do it is want of courage, or of principle.
To know what you know and what you do not know, that is true knowledge.
