Things do not happen. Things are made to happen.
Quality is not an act, it is a habit.
Begin to be now what you will be hereafter.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
Expect problems and eat them for breakfast.
If you think you can do it, you can.
Never complain and never explain.
The work on ants has profoundly affected the way I think about humans.
