I am a beginner guitarist / keyboarder, and I am very motivated but I loose my concentration very fast. My maximum rehersing is one hour and after that I 'm starting to loose concentration. Even afer a break I cant get my mind back on my intrument. I hate that becouse I hear people saying that they play six hours a day practice. I want to play my instrument till I drop dead (but I cant).
Does anyone have a suggestion?
