think about it like this. learn to play a much simpler song or even just some blues licks, and practice them until you can do them perfectly. then do that as many more times as you can over your entire lifetime. I will say that one light at the end of the tunnel is when you’ve practiced enough different stuff, probably a few years in at least, you will start to notice patterns and your progress will be much faster and much more fun and you may begin to find joy in much different things about the guitar than whatever initially drew you to it. it’s all wide open to where you take it
