Go for it now. The future is promised to no one.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
Well done is better than well said.
If you think you can do it, you can.
I can, therefore I am.
Do not weep do not wax indignant. Understand.
Who seeks shall find.
Problems are not stop signs, they are guidelines.
Never complain and never explain.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
