It Made Me
The guitar scales do not have to be difficult to learn if you are playing the guitar. You need to stay determined , focused and disciplined. With anything if you practice you can only get better. It is also important to have a scheduled structure. This will help you become a well disciplined guitar player.
I set out a structure just like this one for myself and it worked. I had started off in high school and that is where most of my practice occurred. I stuck to my schedule and practiced on what needed the most work. It made me a great guitar player.
