I agree. There's not actually a lot of content on the linked page, and most of it is generic stuff you can find searching for "how to overcome anxiety" on any search engine. Nothing specific to being an anxious developer at all (though, I admit, I did not click any of the other blog links links yet).
So I am curious, it seems like you didn't get any value from that article. Do you have some suggestions that might benefit others or some feedback for me? Thanks!
