Paradox

"Now... you can reset the timeline, you can try to fix it, but no matter how hard you try... it's never gonna be exactly how it was. Look, I've learned all this stuff that I didn't know before, okay? I'm not gonna make the same... Mistakes. Yeah, what you just said right there? That is the paradox of time travel, and also the paradox of life. I mean, if I only knew then what I know now. Why have these powers if I can't go back and fix what I broke? We're not gods, we're men, who, for whatever reason, have been given extraordinary abilities. The question you need to ask yourself is, what kind of hero are you gonna be? Are you just gonna take a do-over every time you make a mistake? Or will you live with them and move forward?"
