Get in to medical school, get high grades, get your PhD, be smart, cure AIDS, you'll have more money than you ever want.
Lol... HIV/AIDS is no longer a life-threatening disease. The invention of new drugs (such as Zidovudine, Tenofovir, Lamivudine, and Emtricitabine) have made AIDS just another life-style disease, similar to diabetes and heartburn. Do you really want to get rich? Then invent a cure for terminal-stage cancer. Right now, there are no drugs available, which can cure terminal-stage cancer. And this disease affects tens of millions of individuals every year.
