Re: If you had to get sent back in time to fix something,what would yo
There are some things it would be nice to fix, like 9/11, but how do you do that without getting yourself locked up as a conspirator? And any fix would have to be on the order of mitigation, like getting people out of the buildings----you can't risk stopping the event entirely or the changes to the timeline become too significant to predict at all.
What kind of time travel is this? Replay style, or bodily time travel?
If the latter, it would be trivially easy to prove you're a time traveler from 2011. "Hey, see that guy? He's either my clone, or I'm his future self. Work out for yourself which seems more plausible, but bear in mind I evidently have some future knowledge."
Even then, since I like the indirect results of 9/11, I'm not sure I'd try to stop it. Sort of like a smaller scale version of killing Hitler. Sure, evil is evil and all, but I suspect that the rise of liberalism in the late 20th century is in part, perhaps in large part, thanks to the argument to absurdity against authoritarianism that was Hitler's Germany. Plus, it's not like killing Hitler would stop German militarism any more than stopping the September 11th attacks would stop Islamic terrorism.
If it's the former mode of time travel, having my old body but my present-day mind, I'd do basically what the protagonist of Replay did, and simply make myself wealthy, use my education to make myself appear to be smarter, and my maturity and experience to get myself laid.

As for fixing stuff, if I could inhabit my old body, I could do it, but I was/remain a moron, so I doubt my past self would listen to me if I only got to physically travel back and talk to him, or--at best--he'd manage to find some way to fuck up the advice I gave him.
The solution would be to kill him and replace him, but I think I could only manage that if the time jump was five years back at most. I mean, I'm not aging poorly, but I can't pass for 15.
With that in mind, I would kill my previous self and take his place and go to law school. I imagine I'd do spectacularly well, redoing it for the first time.
I'd go back and keep those sleeping pills away from Marilyn Monroe / or tell her to stay away from the Kennedys (whichever way that worked out...)
And, while I'm in the past, I'd go back a little further (farther?) and tell Jimmy Dean to stay out of that Spyder.
Yeah,
fuck Martin Luther King.
