It's always too early to quit.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.

Always desire to learn something useful.

The dog that trots about finds a bone.

The most effective way to do it, is to do it.

Begin to be now what you will be hereafter.
