Money can lead to happiness.
With money, you have more options. You have more choice in what you can do with your time and energy. When you are out for dinner, you can decide to go to the super-expensive restaurant and pick the most expensive meal without feeling guilty. When you are buying a new car, you are able to get the one that you have always dreamed of – brand new, in black and with all the bells and whistles you have ever dreamed of. When you need a break, why not go on that holiday to Fiji that you have always been dreaming? You have the money.
Spending money on more expensive items now is simply a form of short-term, instant gratification. Longer-term, delayed gratification can result in greater happiness.
