If you can travel back in time...

Plus, maybe stop back and talk to my younger self and give the little guy some advice.

Just don't tell him that. Otherwise there's a good chance he'd lose it.
Wait. but that means he'd be in a mental ward, so you could have never went to talk to him, so he would'nt go to the insane asylum, so...
My head hurts.

Quick question. Say I go back in time 2500 years and do something outrageous... am I able to come back to the time I came from to see all of the wacky results?

I'd most likely save the world from the evil of Nazism by assassinating Hitler before he comes to power , then go back to the Ancient World and stun them with modern technology.

I would kill my ex or destroy him in some way. Other than that...i'd do better in school and stand up to the people I didn't stand up to, and tell them the truth about themselves. Something they can't face. Because i'm not scared to get in a physical fight anymore.

I would:
1) Make sure I never did a ton of crap that I regret now.
2) Persuade my parents not to move.
3) Ensure that I didn't get my heart broken.
4) Have seized the initiative with a guy I was really into.
5) Make sure that I never fell out with my friend when we were 10/11.

I'm pretty sure I already altered the past to change the future in Chrono Trigger.

I'd go back to a minute ago and not click on this thread.

That was mean, RSL. :O

I would destroy the world by creating a temporal paradox. I would convince each of my parents to not meet each other, therefore I wouldn't exist, therefore my parents would be together, therefore I would exist, therefore they wouldn't be together, therfore....and eventually the world and the time-space fabric would disintegrate into nonexistence.

That would be fun.

I would have joined this site along time ago!
