I know I had them with me yesterday and I am reasonably sure they will turn up once again. Having checked high and low at home, at work, and in the car I've decided to let it go. Those are the typical places I put things. Yesterday while thinking of something else (past or future, of course) I failed to note what I was doing during that present moment.
This is a good reminder to slow down, focus on what I am doing, where I am. Not doing so ends up slowing me down more, or creates the need to spend time searching for things I otherwise would remember the location of.
Time isn’t precious at all, because it is an illusion. What you perceive as precious is not time but the one point that is out of time: the Now. That is precious indeed. The more you are focused on time—past and future—the more you miss the Now, the most precious thing there is.
