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
Happiness is the reward we get for living to the highest right we know.
HAPPINESS, HAPPINESS IS THE REWARD

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
HAPPINESS, HAPPINESS IS THE KEY TO SUCCESS

HAPPINESS, BALANCED BY SADNESS
