Everyone starts off making alot of noise. I've never seen anyone pick up a guitar and off the bat hit a chord, let alone play a scale. I imagine the reason any musician plays an instrument is because they love to do it, or their parents forced them to; usually the first of the two. I mean, I didn't start not sucking so badly until I spent 4+ hours a day practicing. I didn't practice because I wanted to get better, I just liked to play. Its really never too late to start playing, I've had my Epiphone since I was about 10 but didn't really get into it until I was 16. Now, two years later, I'm amazed at how far I've come from that awful racket I used to make back then. Its not hard, it just takes time and effort.
