It's interesting how people have different perspectives. I just posted on Lisa's forum thanking her for the exercises in fundamentals 2 that made practicing and learning scales fun. I love them!!!!
But on a more serious note, consider that we live in a culture that has us used to the idea of constant entertainment.
Ask yourself -- are you here because you want to be entertained by the process of learning or because you want to learn so that you can be a guitar player? If it's the latter, which I'm assuming it is, boredom and repetition are a part of learning a new skill, particularly a physical one. Generations of musicians have learned scales and been served by it. You shall prevail as well. ;-)
