The strange thing about thoughts is that most of them are irrelevant. You think them, they flow through the mechanisms of cognition, and then nothing. Nothing comes of it. In the grand scheme of things, whatever thought happened in those irrelevant moments could be replaced by any other thought, and nothing would have changed. Thoughts occupy time, and that is about all they do.
Except, of course, when they do more than that.
Thing is. Most thoughts are never recorded. They happen, take place, and are gone. Some of them are important, some are irreverent, some would make a difference if only they were jotted down somewhere.
But we never get around to thinking we ought to record them. And then they are gone.
Just thought I'd remind you that you still have the option.
