guitar playing.. help?

...(for self learning) when you are up to something, you've got to prepare for it..and in guitar playing, the most important that you must have... the guitar of course!...then you need guitar chord chart...your guitar chord chart would be your guide on what strings to put your fingers on, and what finger to put on..regarding the plucking and the strokes of strumming..you just let it go with the melody or rythm of the song...so this means that you should start practicing with songs you are familiar with...and the ultimate that you should do is...to have somoeone who knows how to play the guitar...it doesn't necessarily needed to be an expert..as long as he/she knows the basics..and you can always check out the internet for some sites to plays the guitar...youtube.com has some video clips of how to do the lead of "sweet child of mine"
