So how do you know what questions are relevant to you? You can answer that by asking yourself this one question; What is my end goal for learning the guitar? Asking yourself that question will help you narrow down the topics that are relevant to your specific goals. If you want to become a professional studio guitarist then you should be learning every scale and chord you can get your hands on and learning to read music. If you want to take a shot at being a rockstar, you should probably be practicing more often than not. If you want to play songs around the campfire with your friends, you shouldn't have to worry about endless scale patterns and chord shapes or be practicing for 8 hours a day. These are all examples of a "big picture" approach. You can also use the same question to narrow down relevant short term goals. For example if you are just trying to learn a few songs to impress your friends, you don't need to waste time learning scales and chords that aren't in the songs you are working on. The overall message here is that all guitarists are different people with different goals in mind. So do yourself a favor and stop worrying about what everyone else is practicing and figure out what is relevant to your own goals. You will save yourself time, frustration and ultimately have more fun!
