Hmmm... That's a tough question.
The best advice that I can give is, take a break from trying to find your purpose for a couple of days. Let your mind wander and let your subconscious catch up with what you've been working on consciously. Your purpose will be there when you get back. Go ahead and sharpen your saw, as it were.
It took me a couple of months of active searching to find my purpose... It hit me out of the blue, and was so simple that it caught me completely by surprise: "To bring peace to everybody."
You'll find yours, don't worry. In the mean time, maybe you could practice some of the time management techniques... The hardest part of them is making a habit out of it.
