Problems are not stop signs, they are guidelines.
Well done is better than well said.
Who seeks shall find.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
