Self-examination and anxiety: Twitter post by Naval

I like the post below by Naval in Twitter. Naval has 826,000 Twitter followers including a number of people I follow such as Scott Adams, Mike Cernovich, Mark Manson, Sam Harris, and Jonathan Haidt.

Just like a low resting heart rate is the byproduct of intense exercise, low anxiety is the byproduct of intense self-examination.

The only thing I'd add is that it needs to be productive self-examination. By that I mean you're looking for ways to improve. I think some people believe they're examining themselves when they're indulging in self-doubt or self-recrimination.
