It is a pleasure to see you make your first post in this community . You are very much welcome to sharing ideas on music and music itself here. It is often a beautiful experience.
It is quite interesting to read your story on your music life. Actually, most musicians had some tough beginnings before they started doing well. I understand also the discouragement that creeps in in the process of learning. But we must learn to continue so as to reach our goal. It is good your friend offered you another cuatro to practice with. I hope to see your skill on it continuously here. You rock!!!
