Do you ever play the "Why"-game?

Do you ever play the "Why"-game? It can be played alone or in pairs. Rules of the game are like this:

1. make a statement that includes "I do", "I want", "I won't", "I must", "I will", "I would", "I wouldn't" etc. The statement must be about you and it must be true according to your best knowledge.
2. ask yourself "why?".
3. answer it properly.
4. ask "why" again.
5. answer it properly.
6. ask "why".
   ...repeat this cycle and see where it brings you to.

Maybe you end up with an answer that you would end up with no matter what statement you started with. What is that answer?
