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
Be happy with what you have and are, be generous with both, and you won't have to hunt for happiness.
You know it's love when all you want is that person to be happy, even if you're not part of their happiness.
Success is getting what you want. Happiness is liking what you get.
HAPPINESS, HAPPINESS IS LIKING WHAT YOU GET
