How to make millions a year?

My dream is to make 1-5 million a year. I know a lot of you are gonna rag on me and be like oh who doesn't but hear me out. You only have one life to live so go big. I plan to major in petroleum engineering which pays around 100k, which I can easily live with if I fail. The only real way to make big bucks is business. Should I start my own business or try to work my way up a big corporation? Petroleum engineers work in shifts so I plan to use my time off as another way to start my climb to the top. Is my plan good?
