I would become a roving traveling robinhood-esque bum, depending upon the kindness of strangers for food and shelter...meeting all sorts of other weirdos and having profound adventures with them. Then I would write books and books about it.
I like to think I'd be doing what I am doing now, which is going to college and studying what I find interesting. However, it is also very likely that if money weren't an object that I would travel the world and write.
I wouldn't change my plans. I still would go into organic chemical research, and teach at a university. I don't care about the money that I will make, I really don't. I am just so passionate about chemistry, science, and all that relates to it. I never cease to get excited about it. It is my calling, and I just want to do it because I love it so much.
