Laughter is a highly addictive positive contagion: if somebody starts, it's very difficult to stop.
You may be cool under pressure and challenge, but can you be cool under success?
Love thyself, so that you can love another. Love thyself so that you cannot project fear. Love thyself so as to let others love you. Love thyself so as to let people near.
Unless you are happy with yourself, you will not be happy.
You are the key to happiness.
Happiness does not have to be deserved, earned, worked for or paid for; it simply has to be accepted.
