Leap, and the net will appear.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
