I know that you like everyone else in the world who is trying to learn guitar, you also wanted to boost that mediocre guitar playing skill up to levels which we could consider very much acceptable. That is possible but only if you are willing to do a lot of things for it. The only way that you could achieve that status is to practice. There is no other way to get there but to practice hard. And practicing hard rather needs much effort. Yes, practicing hard means you should really put your back into it. If you practice half – heartedly, tendency is, you would only learn a little. A good attitude towards practice is really effective. It allows you to learn more rather than just relaxing and practicing only when you want to. That is not a good attitude.
When you fixed all these things and have configured your mind into practicing, the next challenge is to find good lessons. Not all lessons are great, not all lessons are effective in bringing the best out of you. So you better research for a good source of lesson that would really help you in your guitar playing career.
