Seriously, the real answer is nepotism. period.
Don't let anybody tell you different. My father is the CFO of a large company, he got me an internship with said company while i was in college. Then got me job offers once i graduated. Now i'm a CFO for a much smaller company just 5 years later, and the owner happens to be a friend of my father. Nepotism is the path to success, everybody else has to be exceptional at what they do mentor or no mentor. My advise would be to follow the same career path as your most successful relative and use them to get a foothold in that industry. You might want to be an Engineer but if your father is a successful real estate agent, you'd be a dumbass to pursue anything but real estate as a career.
the must sucessful people in my family are drug dealers.
