No matter how careful you are, there's going to be the sense you missed something, the collapsed feeling under your skin that you didn't experience it all. There's that fallen heart feeling that you rushed right through the moments where you should've been paying attention.
Well, get used to that feeling. That's how your whole life will feel some day.
This is all practice.
Lost opportunities, lost possibilities, feelings we can never get back. That's part of what it means to be alive. But inside our heads - at least that's where I imagine it - there's a little room where we store those memories. A room like the stacks in this library. And to understand the workings of our own heart we have to keep on making new reference cards. We have to dust things off every once in awhile, let in fresh air, change the water in the flower vases. In other words, you'll live forever in your own private library.
