I initially bought a few books just to contribute to Justins generous cause, but didn't really think they would be needed as all this is online after all right?... but no, they have actually really helped further my skills along much faster. Just having the song book available when you get the time to play helps a lot (get the ring bound one if you can)
PS If you’ve read this far, then you probably are at least thinking about taking the next step.  Stop thinking about it and doubting in yourself, you want this, so take the action necessary to achieve your goals and  continue towards becoming an amazing rock guitar player right now! You won’t regret at least giving it a try, but you probably will regret it if you don’t.
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. 
Though this decision can be based on preference, we think the best guitar for a beginner is the acoustic guitar. Classical guitars have a wider neck, which can be hard for younger students or physically smaller individuals to handle when learning guitar chords. Meanwhile, the electric guitar is designed to be played with an amplifier, which comes at an additional cost. Acoustic guitars are simple and require little to no additional equipment, making them ideal for beginner guitarists.
