The three parts in this upcoming assignment are designed to start your journey of defining what your purpose is. They're going to be hard to do; and require you to be in an open and positive frame of mind. You should find somewhere solitary before beginning, and will need a pen and paper.
You'll need at least 2 hours per part to do the assignment properly!
You won't need to submit this assignment, as it's highly personal and purely for your own private benefit.
