I won't lie to you, learning these basics can be boring, especially when reading sheet music. This may not sound like much of an incentive to make you learn this, but nobody is going to make you learn these basics, it is totally up to you.
Just remember if you only want to be a hack guitarist that strums a few chords around a campfire with your friends then don't waste your time learning all of this. If you want to be one of the best players in the world, then there is a reason why they are the best, they love the instrument and want to know as much as they can about it.
