Definitely not just true for programming. I design chemical manufacturing equipment (and LED lighting, which I suppose is closer to programming in a way), and find myself constantly anxious about this and that little detail.

I suppose similar to defining what a program would do and why it's possible to make it work... with additional constraints. The constraints might make it a little easier, but for a sufficiently creative engineer it ends up being more like mental aikido against reality whereas for programming it's perhaps like mental aikido versus math...

I wish there were more... you know... examples of "How to relax with blah blah" in the article though. There's nothing here with ideas of things to do, just stating that it's important. That's rather on the useless side, just saying.
