do you think that in searching for happiness, you find more sadness instead? Or perhaps in becoming a more cheerful person, you also had to experience the bitterness of deeper pain? Would you pay that price then? When you achieve a goal but instead of delirious jubilation usually associated with achievements you find yourself confused what would that mean? Hey! Just imagine what would happen if I mismatch all your emotions to wrong situations. You'll never know what to work for again!
I know people always look back at their childhood and say that times were happier back then. Perhaps it is not that childhood was a happier time. But that emotions in childhood was more moderate and mild? Or maybe it just became a distant memory of a hazy utopia we project into our own minds.
