Be kind whenever possible. It is always possible.
Well done is better than well said.
Be gentle to all and stern with yourself.
Who seeks shall find.
Never complain and never explain.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
I can, therefore I am.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
A love of nature is a consolation against failure.
