Is someone trying to tell me something?

It's so hard to tell sometimes if my lack of ability to find the time to write is due to my lack of ability to find something to write about; lack of time to do anything other than work, parent, coach, and sleep; lack of talent or lack of get-up-and-go. Since I don't lack ambition or energy in other areas of my life, I find it very strange that I don't have the energy to write - to finish the last 10000 words of my book or start the crazy awesome new book that's floating around in my head.

What is wrong with me?
