In just 10 months with this group, I have developed more as a guitar player than in the 10 years before this. Now I understand and apply a completely new way of learning, where the brain rewires itself and everything flows through new pathways. If I constantly practice half-heartedly, my brain won't understand the difference between bad and good—it will just follow the paths that are most heavily trodden. And yes, now I have finally learned to play fast and accurately when needed.
