It's always too early to quit.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Quality is not an act, it is a habit.
Who seeks shall find.
Wherever you are - be all there.
What you do today can improve all your tomorrows.
Know or listen to those who know.
God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.
Science already contained all that was necessary, if you just brought it out.
