I don't think it's one skill; it's having your antennae up at all times and sensing what the next big thing might be, as well as actually liking that thing. For me it was AWS. About 7 years ago I was sitting in "Architecting on AWS" and I had an epiphany that this wasn't a game changer, this was a game redefiner. I was jazzed about it and have been pursuing AWS jobs and expertise every since. AWS isn't the end-all and be-all, and it's abused more often than not, but it has provided an extremely lucrative career for me. Also, as much shit as Amazon gets, AWS is a very, very good product, or suite of products. It only gets more complicated every year and my idea of it evolves every year as well. It's still going strong, but I do have my eye on other technologies and am making sure I don't become a dinosaur.
