True happiness from money comes from saving it to achieve independence, autonomy and control over your time, rather than spending it on material possessions. Wealth is what you don't see, such as the savings in your bank account, which provides the oxygen for independence and autonomy. While nice stuff loses its novelty over time, the freedom and independence gained from saving money will never lose their value, allowing you to wake up each morning knowing that you have the ability to do whatever you want.
