What keeps me from writing my masterpiece? How is it that Professor Einstein had time to pick up his dry cleaning and still come up with his special theory? Of course some will argue that he didn't give much thought to matching his socks or fixing his hair. Heck, I don't either.
At this point I can only hope to leave a body of work that explains who I was. It seems wildly conceited to think that anyone will ever care. Hmm.
