I think money is just a something like food: you need it to some amount to have a good life and having a bit more than you need increases your happiness slightly. Having much more, doesn't change much.

There are two very important things to make you happy:

1. Reason and Prospect

2. Freedom (to execute)

Money can increase your level of Freedom (e.g. so you don't have to spend your time working for someone else). A Reason doesn't have to be the reason of your life. It just has to be something you want to accomplish (be rich; be a good parent; be admired; etc.) in combination with an idea to get there (prospect).
