Problems are not stop signs, they are guidelines.
Never complain and never explain.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
The dog that trots about finds a bone.
You never know what motivates you.
A good teacher must be able to put himself in the place of those who find learning hard.
