Happiness does not come from doing easy work but from the afterglow of satisfaction that comes after the achievement of a difficult task that demanded our best.
HAPPINESS, HAPPINESS DOES NOT COME FROM DOING EASY WORK
I do believe that if you haven't learnt about sadness, you cannot appreciate happiness.
HAPPINESS, BELIEVE THAT IF YOU HAVEN'T LEARN ABOUT SADNESS
What we call the secret of happiness is no more a secret than our willingness to choose life.
