Never complain and never explain.
To be a good loser is to learn how to win.
Wherever you are - be all there.
If you think you can do it, you can.
The dog that trots about finds a bone.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
