I know that for me, I enjoy getting to put the spotlight on my students. I also like haveing concerts for my students to be able to demonstrate their skills for their friends and family. I also can work with students of any age, starting at about age 5 through age 100+. My experiences with teaching children gives me the ability to teach even very young students.
Learn how to read tabs. Tabs will have six lines that represent your strings, along with numbers that designate where you should be placing your fingers. The numbers represent the fret in which you need to hold the string down. A 1 means the first fret, a 2 means the second fret, and so on. Numbers in a progression mean that you hold down the first individual fret and pick the note, then move to the next one, and so on in succession. Numbers on the same vertical line are meant to be played together simultaneously as a chord.[9]
Learn barre chords. Barre chords, or movable chords, are extremely useful for starting to play songs. In a barre chord (sometimes shortened to "bar chord"), the index finger of your fretting hand "bars" all the notes at a single fret. To play an F, which is the barre chord in first position, you bar all the notes on the first fret with your index finger and play what is essentially the shape of the E chord moved one step up the neck, with your middle, ring, and pinkie.[8]

After you have selected a style and a teacher, you may want to keep some extra questions in mind for your first guitar lesson. An in person lesson can be very valuable, if you show up, and if you do the work that the instructor gives you for when you are not meeting. One of the greatest methods of improving is to consistently play. Play multiple times a week, get those practice repetitions in.
I have checked out Justin's site and found it to be comprehensive and informative.

Along with his insight into teaching and his fantastic abilities on the instrument, Justin has created a powerful go-to-place for anyone interested in exploring the instrument to their potential. Just don't hurt yourself.
