Things do not happen. Things are made to happen.
Do not weep do not wax indignant. Understand.
It's always too early to quit.
The dog that trots about finds a bone.
The secret of getting ahead is getting started.
If you can dream it, you can do it.
If you've got a talent, protect it.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Never complain and never explain.
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.
