Always leave something to wish for otherwise you will be miserable from your very happiness.
Remember happiness doesn't depend upon who you are or what you have it depends solely on what you think.
HAPPINESS, DEPENDS UPON WHAT YOU ARE
Morality is not the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.
HAPPINESS, HOW WE MAKE OURSELVES HAPPY
Three grand essentials to happiness in this life are something to do, something to love, and something to hope for.
