for you to consistently stop buzzing strings, etc?

I've been with this guitar for about 3 weeks. About 2 hours per night. Sometimes more. I love it. I don't expect this to turn into a 'be patient' type thread as I have no delusions that I'll be, what I would call, a decent player in the next year.

I'm just curious as to how you started when you began, how long did you practice each day or each week, etc.

I started with a nice acoustic guitar, then I joined this site. I've now been doing lots of finger exercises (no sense in trying to play allot of music, until my hands are strong, flexible, and tough enough). I've also been doing pentatonic scales, (blues scales), arpeggios, etc. Just started learning some chords this week. When my fingers or hands are too sore to practice, I'm reading lots of theory on chord construction/progression, circle of fifths, etc.

Am I'm doing the right stuff? I really don't want to go and get lessons just yet if I can get all my fundamentals done through books and the web. :)
