If I were a time traveler who could go back or forward in time, I would choose to go back. What I would do is gather the last ten years of winning lottery numbers and go back in time and chose those numbers so I could win the lottery every single time for ten years. Then I would be richer than Donald Trump and could do almost anything. That would solve a lot of problems im currently having, and I just think that it would be nice to have a boat load of money that I can do anything I want with.
