That sounds a bit hyperbolic to me. There's not a whole lot I would wanna exchange my experiences for.

Basically we're talking about traveling back in time but forgetting all your memories after that point. And without those memories you'd just end up at exactly the same spot where you now are, wouldn't you? Assuming the universe is deterministic. Which paradoxically means you actually cherish those lived experiences so much that you wanna relive them. ;)
