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. 
Try listening to different styles of music for inspiration as you learn to play. If you're trying to learn to play by ear, listen to the blues and try to mimic that sound. Blues progressions are especially great for learning to play guitar because it's built on the basics of music theory. Once you learn those progressions, you can start practicing them in different keys, as well.
Minutes 60-600. Pick up the guitar everyday for 20 days for 30 minutes or so. You can do this while you do other things like watch TV or chit chat. Get your fingers used to moving around on the fretboard. Start jamming out some John Denver baby. Please do sing along. Eventually try to keep up with tempo of the changes in the actual song. Once you can change your chords on time, focus on improving your “touch” with your right hand. Strum the chords in a way that it adds texture to the recording (if you are playing along with the man himself.)
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

If you are practicing regularly, like you should be (at least once a day) be sure to change your guitar strings once a month. You will be amazed at how much of a difference in sound quality a fresh pack of strings will make. You don’t need super expensive strings. When I was starting out, I got by quite happily on my local music store’s house brand of strings that cost about $4 a pack.
