In order to get us in the proper mode of thinking about the book, we'd like you to suspend disbelief, open up your eyes, minds, and hearts, and imagine a world in which our primary purpose in life was clear to everyone. The reason we are here in this world is to work on ourselves, thereby becoming better people. The ultimate goal is to fix the whole world, but we do so, first and foremost, by working on ourselves.
Let's say that everyone knew that, and even further, that we knew exactly in which way we were supposed to improve ourselves. There are certain attributes, known in Hebrew as Sefirot, which are qualities that we are supposed to work on, and these qualities are a reflection of G-d. The more we work on them, the more we become like Him, and are closer to Him. Just as G-d is kind, so would we work on being kind. Just as He is mighty and strong, so do we work on our might and strength, and so on. Further, imagine that we all knew what we were supposed to work on each week of the year, and even each day of the week.
