Started playing guitar when I was 15. Before that I had already been playing piano for some years so I already knew a bit about music.
The first things I did was to learn the basic chords, and then go over to some basic scales (pentatonic, major, minor, harmonic minor etc), and just mess around. If you get these down you can play most songs with basic melodies. Later I learned hammer-ons and pull-offs, alternate picking, tremolo picking and sweep picking bla bla. I never took lessons myself, so I'm pretty much entirely self-taught. I read a lot about guitar and music though, so I would avoid bad habits, and learn the techniques properly, so that I wouldn't mess up anything during my development as a guitarist.
Bar chords can be a pain in the beginning, especially since you have to develop some finger strength in order to pull them off properly. This will take time, but once you get it down you'll start to wonder why you never were able to do it earlier. Now it's the easiest thing ever.
Nowadays I play a whole lot of different genres: Rock, metal, jazz, folk, acoustic pieces. I play music from many genres and different decades. Focusing solely on one genre would get boring quickly.
I love music, both music theory and its history. I play guitar and piano (have a bass as well), and I just love playing them. I have no real musical ambitions, so I'm just a recreational musician. Through out the years I've grown to become quite the skilled musician though, but I only crave more knowledge. Music is definitely one of my favorite hobbies, and a big part of my life.
A dream would be to become a composer one day though. That's as far as musical ambition go.

I guess that is a very very quick summary of me story as a guitarist.
