How Much Time dose Minecraft really take?

How long dose Minecraft really take? How long do you have to play to "Get Good" How much can you are in school or have a job? These are just a few questions that I want to answer in this series. I also want to put into perspective how much time other youtubers put into this game behind the scenes that you never see or hear about. This is kind of just a prolog but hopefully as you follow me through the development of this world you can see the beauty and time commitment that Minecraft is.
