I'm not sure if it sounds like he's burned out. But, it does seem like he's been quite busy and would like to take a break. I can't blame him - looking at his list that he's accomplished in a year and a half - WOW. I don't think most people have done half as much. Plus, looking at the bottom of that list - you can see how long he's been away from his family. How can you blame the guy for wanting to take some time with his family, when it's clear that he's made certain choices and sacrifices to accomplish as much as he did.
