One more thing I'd like to add: If you find that doing simple chord/scale exercises is boring, try spicing them up a bit. My grade-school music teacher used to explain it, by using an analogy to food. The guitar itself is the plate, the boring stuff (exercises) is the vegetables and potatoes, and the fun things (songs, riffs and licks) is the meat, while gigs are the dessert. Young kids usually don't want to eat the vegetables, but if you do something to the potatoes (make chips or fries of them), kids will eat as many as they can with no hesitation. Likewise, if you try to conceal your chord and scale-exercises so they look like something else, such as a riff or some chord progressions, you will still know it's the boring stuff, but it won't "taste" as bad, because it's "prepared" differently.

Now, you may think "but I can eat my meat without eating the potatoes". And that's correct. You can eat your meat and leave the potatoes on the plate, but if you do, you won't grow up to be strong. Alternately, you can eat the potatoes without eating the meat, but you won't get the proteins needed to grow up. Either way, the only way
