Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
Never complain and never explain.
Begin to be now what you will be hereafter.
The wise does at once what the fool does at last.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
The people who work in intelligence work are more conscious, more apt to be attentive.
