Practicing is essential. Playing guitar isn't just something you know; it's something you do! When I was just starting I practiced 30-60 minutes everyday. The more I played, the better playing felt, and after several years I was playing 2-3 hours a day. To play well you need to train and condition your fingers, your ears, and your brain. To do that you need to spend time with your instrument.
Many of my students have trouble practicing a lot, because they don't know what to do. They run through their song a few times and then wonder, "What now?" I solve this problem by dividing big projects into smaller projects. If, for instance, I'm working on a classical piece, I will divide it into small sections. I'll spend 15-20 working on different hard bits. Often the parts that I'm polishing are just a measure long. I'll play the difficult part slowly with my metronome. It is important to practice at slow speeds where even the difficult parts can be played with relaxed hands.
If I am working on a new jazz tune I will usually spend 15 minutes playing the melody, 15 minutes and the chords, 15 minutes on scales related to the tune, 15 minutes on improvising over the tune or small parts of the tune. I might also spend time playing the tune in different keys, or identifying other things I'd like to try.
Dividing big projects into smaller, very specific tasks will help you identify techniques that you want to work on. This will make your progress more rapid. This is much more effective than just banging around on the guitar to see what happens, but I do that a lot as well. It's fun.
