Quality is not an act, it is a habit.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Only the educated are free.
Be kind whenever possible. It is always possible.
Without hard work, nothing grows but weeds.
Go for it now. The future is promised to no one.
If you're going through hell, keep going.
Always desire to learn something useful.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
