I heard this analogy to life being like a school and having different classes with lessons and exams in it a few years ago. Personally, I like to think of it as Earth School. I know. I know. This sounds really wierd, right? Now, before you stop reading let me explain further.
My inner inquiry sounded something like this: How is my life and my experiences within it anything like school? I finished formal schooling years ago. What are these people talking about?
