If I had Twenty Million Dollars

In this world, most people would like to have a lot of money for taking greater life. Due to this reason, they work hard to get promotions and raise the salary. If I had twenty million dollars, I would use them to make more money. For example, I will separate for three parts. In first part, I would buy a house and get regular rent for it. The second part, I would take some investments for more profit from them. For the third part, I would save them with fixed deposit for emergency reserve fund. It is not important to have a large amount as twenty million dollars but how people manage it. If people do not make plan for money management, one day it would be run out.
