I am in your same situation. Been playing for 5 months and can only do very little at the moment and I blame my inconsistency for it.
I recently purchased a book called 'From zero to guitar hero' and it's helping me a ton to move along. It's very simple and gets right into the good stuff.
What I do at the moment is a lot of finger exercise on the guita. I think it's vital to be able to move your fingers around the guitar well and being able to hit scales when you need to without delays.
So if I am watching TV or anything I will have the guitar with me and will keep exercising my fingers.
I think that is crucial. I see a lot of licks on you tube that I could easily do but the problem is my fingers don't move fast enough and don't have the coordination and dexterity to effectively hit the right chords when I have to and the sound is just all over the places.
IMHO finger exercise everyday and pick one song that you like and master it what ever it takes.
In my life I never had a lot of determination so I always start things and never finish them. Now that I am a little older I need to teach my self to stick with one thing and I picked the guitar, since I always loved it.
I look at it this way I am 37 years old and I know I will never become a rock start, it just not going to happen.
I will never be good like people that have been playing the guitar since they were 10 years old and I am fine with that.
What I want is to be able to entertain myself and that is my only goal.
Guitar lessons are good but they are not going to make you a guitarist. No teacher can make miracles and some of them are not good to begin with and might make things more boring for you in the end.
There is no magic trick to learn how to play an instrument, it's all up to you. Like sports and other things in life it's all about repetition and pit bull like determination and a lot of boring hours practicing.
I am trying this song at the momenthttp://www.youtube.com/watch?v=kEMlJ0KFuek
it's a 45 minutes lesson to learn shoot to thrill.
The problem with this lessons is that there is no way to slow down the playback when it's showing the action and that hurts. On garage band I can slow down the playback and it helps me a lot to learn faster.
