I consider myself extraordinarily lucky. I can point to many different instances of luck that enabled me to be where I am now. Hard work and talent are a given, but among those that work hard and are talented, there's a lot of blind luck that determines who gets the few positions that are available. I continually remind myself not to fall prey to the narrative fallacy, and think that I was somehow "destined" for my current position, and that I got here entirely because of my own work. I was not, and I did not.
I know people who did not land those academic positions, and are either in industry not doing research, or stuck in the post-doc waiting room.
