I do all of this, and my personal life has had lots of good luck in the last five years, but at the utter expense of my professional luck. I have had an astounding series of bad luck, especially recently. I do all the things you mention, the article mentions, etc. And still, it seems as if my luck as gone from bad to worse. It's shocking to me. Certainly a large part of this is my fault; I had too much hubris and self-confidence, and was sure if things had been going a certain way, they would continue that way even to some extent. But bad luck happens, just as good luck happens, with no priming for the condition at all.
