Are you a Buddhist? I think your thought is contributed to by Zen of Buddhism.

Maybe happiness is the psychological mood that we experience when our need is satisfied. For example, a boy looking forward to his close friend's email will feel happy when he receives the mail. Therefore, happiness does not mean wealth. The poor will be happy if they have money because they need money. In contrast, the rich with serious disease may not be happy when they earn lots of money because they would rather be healthy than wealthy.
