The most valuable take-away is that there's never really a strategy--if by that we mean something with a well-defined endgame. In academia, you simply cannot say, "I want a job at University X" and devise a plan that will lead you to that goal. The only thing you can do is work hard, build your career, stay ready, and keep an eye out for whatever opportunities arise.
Or as Dr. C. says, using a baseball metaphor:
The. . . reason they teach ballplayers to run out hopeless ground balls is because occasionally it does actually get you somewhere. Sometimes you hit the ball and don't seem to have any chance at reaching base. But then some piece of unexpected luck, some fluke, gives you an unforeseen opportunity. Players are taught to run hard for first base, no matter what, so that they have a chance to be lucky. You need to put in the work before there is any apparent hope; if you don't turn on your full speed until something surprising happens, you're probably too late. If you ever get a sudden bit of good luck, you need to be running as hard as you can.
Too few people get lucky these days, and the job market has many more people ready for their break than it has breaks to give. But any strategy is doomed if it isn't flexible enough to accommodate luck and chance and change.
