Life is full of missed opportunities if you want to think about it that way. Every moment is an expanding tree of an infinite number of missed opportunities.

I prefer not to think about it that way. I used to, and it tore me apart and rendered me incapable of ever focusing on any one thing, never able to enjoy anything, never able to relax. It was killing me slowly.

Every moment is a choice. There's a thousand things you can do, but you can only do one of them. No matter what you choose, there's 999 other things that become "missed opportunities".

On the other hand, every moment I choose not to spend doing one thing, is a moment I get to choose to spend doing something else.
