How can I reignite drive for developing my front-end skills?

In regards to front-end skills, I'm kinda stuck on where I can improve next. I find myself dissecting libraries and building them myself with some tweaks and improvements. To me, it all just feels it's just a matter of time instead of actual skill. The same applies to learning a new technology or new design patterns or concepts, everything becomes a matter of time and I can't feel motivated knowing eventually I will get there.
