To be kind, honest and have positive thoughts; to forgive those who harm us and treat everyone as a friend; to help those who are suffering and never to consider ourselves superior to anyone else: even if this advice seems rather simplistic, make the effort of seeing whether by following it you can find greater happiness.
Don't take 'no' for an answer, never submit to failure. Do not be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes, but as long as you are generous and true, and also fierce, you cannot hurt the world or events.
But reason always cuts a poor figure beside sentiment; the one being essentially restricted, like everything that is positive, while the other is infinite.
