Everyone goes through growing spurts with guitar. Your ability will level off at some point and you think you can't get better, then something clicks and all of the sudden you can play faster, or pull off a new trick... or all your old tricks sound better. It's just the nature of the beast. Practice is the key to improving. Target what you want to get better on and practice just that for a week straight. Example: Practice just scales for a week. Run through them as fast as you can, concentrating on what scale you're playing and think about the notes while you play it. This will help you learn the scales, the notes, and play faster and more accurate... Also concentrate technique!!! One finger per fret, using your pinky. Once that week has passed, move into something that has to do with chords. Get a book that has some theory on chord structuring and chord building and start strumming chords. Try to use a drum track or something that you can strum to. This will get you use to keeping time with your patterns. Then, the next week... get some backing tracks and start messing around with improv. Use different types of music... blues, rock, and metal... just some examples. Then the next week... come up with some of your own chord progressions and riffs that you can use in jamming. If you can, record them and jam over them a whole bunch. This is a four to five week plan that I've used in the past to get myself out of a rut. You will notice that when you take some time off from playing, sometimes when you come back to something it will seem easier. Good Luck
