I can't remember where or when or why, but I do remember thinking
"if only I could be like that,"
"if only I could have that kind of life,"
"if only I could behave and act in such a way that was a better reflection of my own deep down as-of-yet unfound ideal personality type,
as a better version of myself; the me I want to be but can't even imagine being:
then I'd be happy."
Come to realize that I have become that version, but just as I've changed, so has my own ideal version of what I could be (which is to say, that despite achieving vaguely recalled dreams, I'm still not happy.)
It's like running a race against yourself,
surrounded by wraiths of what you could-have/once-were/will-one-day-become running in the other lanes.
The trick is to close my/your/our eyes and meld them all together;
the key is to maintain this pace.
"*******, I'm going to make it!"
