Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
To get good touch in your strumming hand, it’ll take longer than 10 hours. It’s about reps. Try to consider the amount of finesse you are hitting the strings with. Do a little research on palm mutting and other useful strumming techniques. If it sounds nasty at first, that’s cool. Your fingers and wrists will start to adjust. Focus on getting quality sounds out of the guitar.
Learn the difference between chords and single notes. Chords occur when you play two or more notes on different strings simultaneously to create one unified sound. These are what make up the "rhythm" portion of acoustic music. Single notes are used more for solos and occur when you play a single note at a time. Both are skills that you must become proficient in when learning to play the acoustic guitar.
Acoustic: I recommend a Yamaha solid top acoustic guitar. This guitar plays just as good as some that are many hundreds of dollars more expensive. It can be difficult to manufacture quality acoustics at low prices due to the importance of a solid top finish. When I was in college I scratched together the cash to buy a handmade acoustic guitar that was over $1,000 (I won’t mention the brand) but that guitar was nowhere near as good as this Yamaha.
You do not need long fingernails to play guitar. In fact, it's best to keep your fingernails short! As for the callouses, these may be unavoidable. If you would like to avoid them as much as possible, ask your guitar instructor about lowering the action of your guitar (the action is the distance between your strings and your frets) so that the frets are easier to press down on.
I've seen so many guitar lessons where the instructor simply dives right in and begins teaching chords. Unfortunately, that assumes that the student's guitar is already in tune! Guitars are made out of wood, and wood reacts to our environment, be it hot, cold, dry or humid. As such, guitars frequently go out of tune, and they must be tuned to make them sound good. If you begin learning to play guitar on an out of tune guitar, it will not sound good to the ear no matter how hard you try, and as such, it will become discouraging pretty quickly.
Justin, first off I just wanted to say thanks for all the advice and instruction. You make playing guitar easy and understandable and fun. You explain very well the hows and whys when presenting a new song to learn and walk it through so that anyone can learn. I have played guitar for 20 years now and have learned more from you in the last five years than the previous 15 by myself. You have also been a tremendous help to both my son and my daughter in learning to play as well by making playing fun and interesting. I have a couple of pictures of me and my children all doing what we love. Many Thanks to you Justin
I use a completely new age form of teaching that really clicks with all my current students. It is a mixture of traditional teach and a computer program I use for teaching. Kids seem to pay attention more when I have the music on a screen rather than paper. The main goal I have with every student is not teaching them how to play everyone else's songs but how to utilize these techniques and shapes to create their own music. I'm in 3 bands A Tragedy At Hand, Behold my Majesty, and Take the Reigns all are on Facebook. I have shared the stage with bands such as Slipknot, Judas Preist, Veil of Maya, Born of Osiris, Arch Enemy and so many more.&nbs ... View Profile
I would especially like to stress the gentle approach Justin takes with two key aspects that contributed to my development as a musician - music theory and ear training. Justin has succeeded in conveying the importance and profoundness of understanding music both theoretically and through your ears while maintaining a simple and accessible approach to them, all while sticking to what is ultimately the most important motto: 'If it sounds good, it is good'.
