I sounds like you are at the perfect age to start pursuing your dreams of playing guitar.

I you want advise from someone who did it wrong, then make sure you actually learn guitar. The fret board and names of all the notes. Learn different styles of playing, so that your music becomes a conglomeration of those styles, and not just a repeat of something you heard.

Dedicate time to it. There are many great lessons on this site, from what I have seen so far. Start at the beginning, practice every day.

We have both seen good players, and I know they were not born with the talent. They worked for it.

Nice meeting you!
