本周早些时候, 他曾经在推上说: 我喜欢征服艰巨目标时的感觉, 因为你知道你已竭尽全力. 有些人会认为我疯了, 但驱使我向前的动力或许是, 我想看看自己的极限在哪里, 我究竟还能走多远. I enjoy the feeling when you accomplish something which is hard. Knowing that you pushed yourself to the limit. Some people think I'm crazy but maybe what drives me is to see what my limits are and how far I can go.
