Without hard work, nothing grows but weeds.
Problems are not stop signs, they are guidelines.
The wise does at once what the fool does at last.
Quality is not an act, it is a habit.
Know or listen to those who know.
If you think you can do it, you can.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
Think with your whole body.
