Learning to play the guitar is a life-long process; it will not happen overnight despite what many of the hucksters on the internet may tell you. As such, you are best to develop some reasonable expectations of how quickly you will progress. There will be challenges along the way (yes, your fingers will hurt!) and too many budding guitarists have given up prematurely, slid their brand new guitars under their bed, and walked away in disappointment… not realizing that they were oh-so-close to a breakthrough that would have taken them on to the next level. Having a mindset that allows for setbacks here and there will really help you in the long run, because you will find that through every challenge you come out a stronger player on the other side.
I love love love these guitars. No gimmicks. They are pure class (but are capable of absolute fury!) :) Think a Telecaster can’t rock? Johnny Greenwood respectfully disagrees. Check out Bonnie Raitt using a Strat to lay down some nasty slide licks. SRV nearly tears the strings off his Strat. Would you prefer something a little funkier? Here’s Prince playing the greatest guitar solo of all time on a Telecaster.
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.
One other cool thing about electric guitars– you can plug them into your computer and use a program like Apple’s Garageband as an amplifier. You can basically have 100’s of classic sounds available virtually. You can “jam” virtually with your computer and create full-on recordings on your laptop. You’ll just need a “pre-amp,” which is a device that amplifies the signal from your guitar before it sends it to your computer. I’d recommend something like the Focusrite Scarlett
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.
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. 
I tried several times over the course of 20 years to learn guitar. I purchased guitars, amps, books, private lessons. Nothing ever stuck, until I found justinguitar.com. The only reason I can play guitar today is because of Justin. His courses are well thought out, easy to understand, easy to follow, and easy to make progress on. I can't think of a single product or service that I've ever used in my life that I could recommend more highly than justinguitar.com.
I've started off a new series with the awesome Ariel Posen, The Captains Privates series is popular as ever and I've also been filling in some beginner lessons of things I get asked about all the time... I'm about to re-kindle the Blues Lead 3 series which fell off the wagon somewhere and also get the gear videos rocking again... so lots in the works, lots going on and still loving it!
Use tabs instead of sheet music. If you don't already know how to read music, it can take a lot of time to memorize and proficiently read sheet music. Tabs are an easier and more intuitive way to write music for beginners that doesn't require any formal education. Tabs will simply tell you where to put your fingers on a fret board and how to generally play a song.
