Guitar lessons for beginners like you can really help especially if you focus on your weaknesses once in a while. Of course, you will not be able to know yourself well enough to know your weaknesses if you don’t assess yourself.
Thinking about what you can and cannot do is not totally a bad thing to go through sometimes. Do not get me wrong, you will not do this to count the things that you are capable and not capable of doing, but you are doing this because you want to be aware. When you already become conscious of the things that you cannot do, it will be easier to learn.
This may seem ironic but you should not be deceived by these weaknesses because they guide you to become a better guitar player. Sometimes the awareness to your weaknesses can even help you improve your playing without you even noticing it. Of course, guitar lessons for beginners would require them to go through a lot of adjustments. Like for example, if you feel awkward whenever you hold the guitar, you have to discover why you are feeling such a discomfort so that the next time you hold it, you will be more conscious of what is going on. Maybe your right arm is feeling stiff whenever you try to strum and pluck a few chords, then you can support your right shoulder until you right arm feels more comfortable. It really depends on your feel on the situation.
Whether it is a good thing or a bad thing, remember that acknowledging them is always for the best. You just have to be reminded that it is all up to you to decide how you are going to use these realizations for yourself. You can choose to use them to make you better, or use them to pull you down; either way, it is always your decision.
