I don't really think I have a general inspiration...
I have musical inspirations though. Jake Kiszka has to be the most notable one at the moment, he's a guitarist from an up and coming band (they've blown up quite recently, and quite frankly, I worship them). The guy is the same age as me but has apparently been playing guitar his entire life, and it shows. I'd go as far as saying he's capable of being the next Jimmy Page, he plays so effortlessly and his riffs are so god damn catchy. It's inspired me to keep playing, and I honestly think this guitar playing is the only thing keeping me going right now.
I had the privilege of seeing him live a couple of weeks ago, on the rail, on his side. Safe to say I stared in awe for the entire show. Met him afterwards as well. He's a really down to earth guy, clear that the fame hasn't taken it's toll yet.
