Once I too felt like that.

Maybe you're just into something different. That's ok.

But maybe you're like me: For my case, it turned out that I was just bored of doing what I'd been doing. I changed my direction and left full-stack development. I started studying machine learning (and lots of other stuff because of it), bought some in-depth books about programming and started reading them. I finally understood the importance of Lisps (yes, the weird syntax has a really good purpose) and started learning Clojure. I'm constantly trying to improve my -functional- programming skills. It feels ok now, I feel like I've found a new path to follow, and see the room for improvement.
