Have you ever thought about that question? If you think about it, it really is the central question to life. But why you may ask? There you have proven the point because you can't ask the significance of the question without using it.
Simply put, life requires meaning and in order to discover its meaning, you must ask why. I have been asking myself a nonstop series of why questions: why is it that I have chosen this career path? Why do I force myself, against my nature, to get up at insanely early hours? Force my brain beyond its limits for hours on end? Stay up too late doing things that don't matter and then even later organizing myself for things that do? Fluctuate between such extremes of emotion and purpose? Why is it that I set such high, detailed plans only to be so easily swayed by those around me? Why? Because this stubbornness that is my character is a battle, and I'm losing. Innevitably, my more stubborn side defeats my stubborn side and I am left in the middle, feeling both triumphant and despondant, not knowing whether the better half of me has gained ground or lost it. So the answer to all those why's is simple, after all it's complexity: I don't know. Or maybe I do, I just can't remember. So I pose the question to you; answer it how you will.
