I'm not a true beginner as I've played acoustic guitar before. Just by learning chords and a few tricks from friends. Nothing special. To cut the story short, that was about 20yrs ago. Recently, I've decided to take lessons. Mainly, electric guitar lessons. I wasn't sure if that was the road to take or just learn from online websites like this. I had my first lesson (1/2hr). It was nothing special, just basics, but I've already learned a couple of things. So yeah, I think taking private lessons is going to help a lot. What helps me now are a few things:
1. Private lessons (1/2hr lesson for me each time for only $15. Once a week)
2. Learn from websites like GT.
3. Read all you can about what you need to know from other websites. For e.g if I don't understand what is scale, I lookup at google and found the definition of scales.
Also, practice, practice and practice. There is no shortcut to being a good guitarist. I had to tell myself be patient. Set aside 1/2hr each day to practice.....if you can practice more than 1/2hr, sure, why not. Just don't let guitar practice get in your normal life.
Hope this helps. Good luck buddy!
