I think what Poseidon is saying is that a number of pieces of advice have been endorsed by many and that is probably the best we can do here. The first one is that a teacher (so long as he has a bit of experience) is what you need to progress further. YouTube is fine and you should give it a try if it is difficult to find a teacher near you at convenient hours. I will be taking lessons myself as I am in a situation similar to yours. The second one was to select easy practice songs first and work on small pieces at a time, trying to make them sound good (forget about sounding like the records - if you compare studio and live versions of most songs you will see that many times even the original artists are not that close because of all that is involved in recording and producing an album). Guitar heroes like Friedman tend to always play difficult stuff or, when simple, make it sound so different from regular players, so best to Google "easy guitar songs" and "your genre" or find simplified arrangements. Good luck.
