For me, there would have to be 2 answers depending on one small thing... would I remember what happened if I turned back time? If yes - Then I would turn back time, learn as much stuff as possible, and repeat until I know as much as possible. If no - Nothing as I would not remember that I turned back time.
I have no regrets, I wouldn't change anything. Except, I might like to play mass effect again for the first time.
Take a perfect copy of the stock market from 1990-2015. record all major sports victories. Best a bit of money to earn some starting funds on a team that is unlikely to win, then use the profits to invest in the stock market and become pretty rich, but not insanely so. proceed to live life without the constant need to make money in order to survive. Use most of my richness on making my own non profit charity specifically to get people under the age of 25 out of any school loan debts. instruct myself in game design principals. go work for riot games even though I don't need the money.
If I may say, great idea. If I would have only thought about this when I posted mine, I would have said this. (Well, everything up to the point of a non-profit charity.) *Really bad joke warning* Guess now I would turn back time to change my post.
Real life; I would probably take the opportunity to re-do my final year of high school and live a little bit more. I never really ventured out and did most of the fun things you see most high school kids doing. I think I focused a little too much on my school work and a little bit less on myself and I wish I could change that now that I'm going through post-secondary. However I guess you can say I'm doing just fine now but I still do regret not living a little when I should have. EcoCityCraft; I'd obviously abuse the fact that I could go back in time knowing the outcome of sports books and the stock market to make myself filthy rich.
On ECC, I'd go back and stop myself from loaning money to Caliki123 (now KieranXGaming) and Spentza (I still have hope for him to appeal, as there are no hard feelings between us). Also, I'd go back and get a screenshot with me as a builder. In real life, I'd go back to the beginning of spring and spend more time with friends (I didn't take as much as an advantage of Spring Break then I should have ;-. After that I'd kill both of my space-time clones to avoid suspicion.
Sorry about this, but if you killed your "clones" (They would be you, not clones, but anyway.) you would end up creating a paradox that would ruin space-time as we know it. (You would now be dead thus not allowing you to travel back to kill your self.) Unless the multi-timeline theory (Possibly hypothesis, don't care enough to figure it out.) is true.
It's a meme, basically showing that I didn't understand a word you said xD Because the guy is 'far out' if you know what I mean
Sorry, for some reason I did not get an alert from your post (or missed it.), just saw it from SuburbSomeone rating my post. Thanks for informing me though.
