Strangely enough, I rarely worry about existential things (meteors and the like). My experience of worry is usually worry about minutiae that I escalate in mind to near existential level.

Now, I often end up feeling pretty proud of myself when plans work out smoothly because of excessive preplanning or hyper vigilance on my part.

However, I also notice that I can get very worried about a small thing -- is that infected cut on my kid's toe going to turn into something way worse? -- when the reality is that it will not turn into something way worse.

I don't want my kids to pick up some level of hypochondria about small cuts. I believe they will be better humans if they have more realistic levels of concern about their health than I generally do. I also believe they will be more effective in life if not as prone to worry as myself.

I hope that my worry makes me a better father, but it does take me out of the moment.

Over the last few years, I've really been quite consciously trying to reduce the amount of time I allow myself to spend with worry. I think it has largely made my life better.

But I take your point taking action on the source of worry. In most cases that is the best course of action.
