It's always too early to quit.
Only the educated are free.
Be kind whenever possible. It is always possible.
The dog that trots about finds a bone.
To be a good loser is to learn how to win.
Begin to be now what you will be hereafter.
Well done is better than well said.
Quality is not an act, it is a habit.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
In any of the arts, you never stop learning.
