Possible Reasons why I haven't yet had a future version of myself stop me from doing something stupid:
Future me knows it will all work out in the end so he doesn't bother.
The paradox of interfering with his own past prevents him from coming back in the first place, making it impossible.
Time travel is not publicly available before he dies.
He has a limited number of trips back and this particular mistake doesn't warrant one of them.
He's actually already here, influencing events without my knowing.
That's just not how it works.
These are the sort of things i wonder as i traverse a strange neighborhood at sunrise.
That, and how much I wish the last bottle of champagne was actually a R250 cheeseburger.
