A lot, I'm finding, but it can be summed well with: I wouldn't redo my life, I'd treat this as an extension. I'd attempt to push my family towards less destructive tendencies, try to find and comfort my future-friends, and maybe try to guide my city towards a more productive future.
Not much truly changes other than my access to more time and power. My reality will still consist of the traumas I've experienced and having a chance to change the events will never make what I've experienced go away. Still way better than now, though!
Those kids will have to be exposed to the world eventually (... r-right?). Converting them to help spread love based on empathy and morals rather than rhetoric seems like the fastest route in my head. Fight fascist propaganda with our own~
However, idk how to reach them lol. Memes n pray? XD
