If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Wherever you are - be all there.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Well done is better than well said.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
