Well, maybe your life didn't impact the time line on a large scale, but then, maybe you can't see the impacts. You touched lives while you were alive, Ray - or in your original time, anyways. Those lives you touched, they were changed.
Why does the change have to be big to matter? I think so long as you helped one person, one person at all, or even just made someone smile - that's a positive thing to leave behind. And honestly, your life only has meaning if you believe it to. No one else can give you that, Ray.
