Just a small piece of advice as you start learning stuff:
Remember that no matter how good you get, you will never feel you are good enough.
Thought I'd mention that, like yesterday, I was noodling on my acoustic and lamenting how rotten I thought my playing was. My wife looked at me this that 'you're on crack' look and said, 'Some never even get nearly that good no matter how hard they try'. Not that I am all that and a bag of Dunlop picks but she made a point. Guitarists that get better are never satisfied.
That's the point, that's ok...learn to make that part of the fun. It's challenging but when you sit down and can bang out something that sounds good, it's a great reward.
Enjoy and remember that even if you can't play it today, with practice, you probably will tomorrow.
