Mainly what you have to do when you first start, is learn actually what a guitar does. Then you['ll have to learn with chords, picking, strumming, etc.
But, this is the right place if you wanna learn, my friend.
there are tons of free lessons, tips, and tricks. And unlike other sites on the internet, this one has video and audio lessons. (but only if you are a high bandwidth subscriber)
But listen buddy. Learning to play guitar takes a degree of concentration and you gotta be patient. A good way to get off to a good start is find a guitarist that inspires you. Then imitate what he does. Dont go picking a experienced guitarist like John petrucci because trying to learn his guitar riffs at a begginner stage will only lead to frusteration, and you would pobubly give up. So pick somebody easy like "kurt Cobain" .
So dont get discouraged, do some of "guitar tricks" leasons.
And mainly have fun
