Why am I going to my job today

I was reading an article, Do It Now, which talks about time management. One of the first points the article says about time management is - Clarity is key. The first step is to know exactly what you want. I thought to myself, "Why am I going to my job today ?". I tried to think of a good reason what my current job will let me accomplish in my life and I have not been able to come up with a concrete answer. I will think about this question some more for a few more days and see if this job is aligned with where I want to go.
