The key to a happy life is to learn how to reduce the amount of things you own and how to build strong relationships. Once you have enough to put a roof over your head and food on your table, more than that can only be used to purchase increasing amounts of comfort, which is not the same as increasing amounts of happiness.

YouTube has plenty of videos of people calling in with hundreds of thousands to millions of dollars a year in income and somehow they are still broke and in debt. Live below your means, save the excess income into an investment portfolio, keep doing that until you have enough money to live off the interest. Don't even think about buying a Rolex until you have so much money coming in from interest that you don't even know what else to do with it. Even then, remember that the Rolex, like anything else, requires maintenance, but that if you make someone else happy, they can take care of themselves.
