I don't think that it's possible. Traveling through time and seeing my own self doesn't seem possible.
Now, it's cool to think that time can be changed. For example, someone with the power to change time can make it either go backward or forward for everyone. So, rather than one person going backward or forward in time, time changes for - and affects - everyone. It would also be cool if you could choose who remembers what time they were in before you changed it. I don't know; just something fun to think about. I don't even know if I'm really making any sense. But simply put: I don't believe that time travel is possible.
Essentially, I subscribe to this idea:
Namely, while yes, you can go back in time, you can't actually change anything relevant. So yes, Nazi Germany murders dem jews, you go back, but the only change you ever affect is some minor detail. Like calling it 'Cyclone-B' instead of Zyklo-B (Or whatever.
I also don't think FTL theory is correct. I don't imagine the universe has a 'speed limit', but rather light travels at that speed simply because of the energy that reaction gives it. So powering your space ship with antimatter will give it a faster, all-be-it more explody, way of getting around. But that's just some random thinking.
So could we travel back? The thrust of it, for me, is probably, but what people seem to forget ("Where are all the timetravelers then, dickhead?") is that we don't have a perfect system of records, so as a time traveler, I could easily jump into 2010 America, play some poker, have abit of sex and easily jump back again without anyone even batting an eyelid. Or, in more internet friendly jargon, only the trolls would appear in our history and seeing that there are thousands of trolls in our history, I would wager atleast one is a goddamn time travelling dickhead.
Also, if a time travelling dickhead is reading this response, the lottery numbers for the next three euromillions (UK lottery) please. Also the plans for the time machine. Dickhead.
