To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
It's always too early to quit.
After a storm comes a calm.
The wise does at once what the fool does at last.
Never complain and never explain.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Expect problems and eat them for breakfast.
Pessimism is only the name that men of weak nerves give to wisdom.
