guitar retry

I decided to try and re-ignite one of my favorite hobbies from college.  So I picked up my guitar, plugged it into the amp, and played a few chords...

...I still have knowledge, but, I can't lose myself in the playing the way I used to.

And even though all my adjacent neighbors are on vacation, I was still self-conscious about how loud the amp was.

Is it time to sell my gear and give up, or is there something I can do to jog my creativity once again?
