Guitar: Stuck in a Rut

I've been stuck in a rut with the guitar for quite some time now. I'm not progressing any at all with learning anything new at all. I even took a break away from the guitar for a few months and when I picked it back up, I realized I was still uninspired. I'm not sure what's killed my progress nor do I know how to grasp the motivation to pull myself up and out of this rut.
