Never complain and never explain.
Only the educated are free.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
Be kind whenever possible. It is always possible.
Without hard work, nothing grows but weeds.
I do not want to go into its physical reasons: the construction of the human body is different from that of carnivorous animals. But man's intelligence is such that it can be utilised to defend any-thing he does, whether right or wrong.
