I have heard how giving you are in so many respects of music schooling and I must say that I am impressed. You remind me of the pure idealism that we had in starting Apple. If I were young, with time, I'd likely offer to join and help you in your endeavours. Keep making people happy, not just in their own learning, but in the example you set for them. 
Practice at least 20 minutes 6 days a week. Consistent practice will allow you to improve your guitar playing skills over a short period. Taking long breaks and not staying dedicated will wear away your muscle memory and delay the development of your skills. Instead, dedicate 20 minutes to an hour of practice throughout most of the week. During practice, you can either run different drills or you can try covering a song.[14]
I have checked out Justin's site and found it to be comprehensive and informative. I have always felt that learning about music and especially music theory applied to the guitar, is helpful in finding your own unique voice on the instrument and expanding your creative horizons. 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.
In order to play your favorite song, you’ll need to learn guitar chords. Use the images and instructions below to learn how to play each chord. The ChordBuddy device can be used for assistance in knowing where to place your fingers In the images the circles represent where you will be placing your fingers (I=index, M=middle finger, R=ring finger, P=pinky). The X’s represent strings that you will not be strumming while the O represents strings that will be played without any frets.

Open up audio for the riff and follow the tabs. Open the song that you're covering in another window on your internet browser. Play through the song and trace the chords and notes with the tab that you looked up. Try to follow the numbers on the tab with the notes that are being played in the song. Try to get an understanding for which chords the artist is playing before trying to duplicating it.

Practice fretting the strings. The frets are the metal strips that run perpendicular to the strings that mark each note. To play a note, press your finger down between the metal strips, not on them. To say that you're playing the third fret means that you place your finger on the string in the gap between the second and third fret. If you hear buzzing, move your finger away from the lowest fret and closer to the higher fret. Hold the string down firmly so that it only vibrates between your finger and your strumming hand, with the tip of your finger doing the pressing.
I’m not going to walk through each of these chords individually with you, because you should be able to figure out where to put your fingers by looking at the diagrams. Once you’ve got each chord sounding nice and clear, then you can begin working on changing between the chords. You can switch between all five of these chords in any order you please and they will sound good together. There’s a reason for that, but we won’t get into that just yet.
