Have you ever tried to learn your guitar lessons and never achieved good results? Are you the type who quits easily for the simple reason that you are not making the progress that you expected. Or you are with the group which feels Mr. X could not make it so it is not worth investing? All these perceptions discourage you from making it to the end. The under mentioned points when well studied will iron out things for you.
The first point to consider is to get a reliable instructor. Little enquiries that you make about the instructors will pay off in the long run. Checkout some track records of the instructors. You may get it from qualified guitar players. "Please where did you learn your guitar lessons?" This may seem a simple question to a good guitar player, but his answer need to influence your choice greatly.
Once you have made your choice you have to believe in the instructions. Your guitar lessons need to be followed systematically. Be happy with any stride that you make in your learning process. Experience has shown that those who rush and gasp for new things do not end up well. You must be slow but sure.
The last but not the least point that I will discuss is about practicing your guitar constantly. What it implies here is that from the word go, you need to acquire a good guitar suitable for the lessons that you undertake. You have to start by practicing to the hearing of your children, spouse, and friends and welcome their constructive criticisms.
The need for all the above is to build confidence in the sys tem that you are following. The great guitarist around us started gradually like you before emerging as great heroes!
