There are only 3 levels of being rich.
It goes something like this:
1. Being able to buy the essentials - food, water, shelter
2. Being able to go to the grocery store and not have to check the prices
3. Being able to do choose what you want to do - travel, buy luxury, not work
There's no practical reason to chase money after this (in my opinion). The only real reason to gain more is to feed your own ego.
Re-evaluate what "rich" means to you. You don't need to have a lofty goal of having millions or billions of dollars. After a certain point, making more money won't make you any happier.
