My skills were inadvertently stuck in 2013. I guess that I sort of knew this, but I didn’t completely comprehend it until I picked up a few books and started diving into today’s standards. I would think that this is relatively common. Even if you want to keep up, you still need an outlet to practice those new skills. In my case, I’ve been working on a demo for a new project, and it’s been quite enjoyable to be able to apply the latest and greatest to what I’m working on.
