"Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life."
Dr. David M. Burns
"When one door of happiness closes, another opens;
but often we look so long at the closed door that we do
not see the one which has been opened for us."
-Helen Keller (1880-1968)
Unfortunate is he who cannot gain a few sincere friends during his life and more unfortunate is the one who has gained them and then lost them (through his deeds).
