A purpose is one, but to be two.

While replaying deep intellectual conversations over in my head one day, I seemed to have a break through on what a purpose is.

Now, many say life is played on one main purpose. With many other small purposes piggy-backed on.
Well, after contemplating this theory I began to see problems with as with many theories. And eventually concluded- there is not one; but two main purposes.

I came to this because life is both made up of a good and bad. Correct? Well, let's put in the terms of whats easy and whats difficult.
Humans often resort to easiest things first, right? Well, what seems easier in early stages of life?

Good = Pleasing everyone, included yourself.
Bad = Pleasing whoever.

The bad correct? Thus, our first life purpose begins after we learn to start growing into ourselves which is in our late adolescent years. Which eventually as all purposes do, they end. When your first purpose is complete, you find half yourself. You are half complete.
Next, after sitting in your early twenties or so of a limbo place- not sure where to go. You stumble onto your second and last main purpose. The good. This is where after this purpose you will be complete. You've found your other half to complete your whole. Such as marriage, a job, and etc. You've found your entire self. This is also where, you have completed life.

So, what are you views on this theory?
