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 not a reward - it is a consequence. Suffering is not a punishment - it is a result.
HAPPINESS, SUFFERING IS NOT A PUNISHMENT
Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
Be more dedicated to making solid achievements than in running after swift but synthetic happiness.
HAPPINESS, DEDICATED TO MAKING SOLID ACHIEVEMENTS
Success is getting what you want. Happiness is liking what you get.
HAPPINESS, HAPPINESS IS LIKING WHAT YOU GET
The word 'happiness' would lose its meaning if it were not balanced by sadness.
HAPPINESS, BALANCED BY SADNESS
