Guitar is hard. It takes months or years of practice to even develop the finger strength and speed to play some things. I always had fun learning in my early teens, because I wanted to, even though I was terrible. Then after 2 or so years of playing every day it became really fun and I was able to get the ideas from my imagination to my fingers.

It’s like a lot of things worth learning - you have to really want it, and it’s never as easy as it appears.
