If you could do it all again, what would you change?

I was thinking about time travel recently, and that question popped into my mind. (yes, I’m a dork)
I mean, we know time is linear, not circular, so we can’t travel back in time. The best we could do is observe the past.

But… if I could go back in time, what would I change? Anything? I’m sure if I thought hard enough, I could think of many, many things. But then I would be changing myself, since who I am today is influenced by the events I’ve experienced. (I won’t even go into the idea that those changes might lead me to not even create a time machine, therefore creating a horrible paradox that could destroy the universe, or at the very least myself)

The scary thought? What if the me of the future has already gone back in time, and the life I’m living now was the best Future-Me could do?

What kind of crazy messed up life must I have lived?

Or worse still…what if I was living the perfect life, but arrogant Future-Me thought he could go back and make it even better, yet succeeded only in completely screwing it all up?

Damn you, Future-Me!
