I used to be a very bad worrier --no, it would be more apt to say that I was very good at worrying, and did it a frightful amount of the time.
There are still moments where I become anxious about some upcoming event, but for the most part I now give rare, very selective fucks. Probably 95% of them come down to pure logistics: Can I get from point A to point B by X o'clock, and do what I need to do there before rushing off to point C for (X+1) o'clock? (Not surprisingly, I am more likely to be 20 minutes early than 1 minute late.)
