That is one of the beauties of guitar playing. It is the challenge. You will see that even after 10 years of playing, there will be things that you will see and think, "wow, I don't think I will ever be able to do that." Yet, trust me. ON the guitar, if you give it time and practice, anything is possible. After the impossible has been done, you can just go and find another goal. YET, the most wonderful thing is..... the goals will never end. That is the beauty of it.
