I read the article several times and couldn't find any references to schedule or workload. So I don't think when he talked about "getting tired" and "an ordeal", I don't think he meant anything nearly so banal as that. Based on what I know of his background and the things he's been most frustrated with in the time since his nomination, it sounds more like he's talking about a more psychological exhaustion that you can have in spades if you work 20 hours a week or not at all if you work 80, depending upon your background and current stressors. I think if I'd been through everything he's been through and knew that a significant portion of the country had absolutely no sympathy for me, I'd be a little worn out too.
