Hmm I also remember him saying that at one point, he just wanted to give up.
I was discussing this with my bf the other day as to why Yuzuru is competing so hard in this GP even though he could really just make a comeback at nationals/worlds. And please feel free to discuss this because what my bf was interesting based on the knowledge I've fed him about the way figure skating works, technically and politically.
Yuzuru wants to avoid the Yuna and Patrick effect. Hear me out. Yuna had one goal in mind when she moved to Canada, 4 years prior to Vancouver and it was to get that Olympic gold. Afterwards, even with all of the programs she's put out, you can see that she's lost that spark/fire/whatever it was that kept her skating. She was skating, at that point, out of obligation and for winning Korea's spots in competition. She disappeared off the radar and off the judges' radar with her few appearances. Yes, she won Worlds 2013 but a lot of people thought she was under-marked during her short program and we all know that starting order does, to an extent, matter.
I digress, what I'm trying to say is that because Yuzuru wants to go on to compete for a second gold medal at the Olympics, he wants to put himself in front of the judges as much as possible, even at the so-called small events like CoC to him has a big impact on the layout of things in 4 years. Yuzuru's known for following "paths" that were laid out by other skaters in order to set himself up to be successful so I can see him sort of analyzing what happened with Yuna and what happened with Patrick going into Sochi (reigning World Champ for 3 years in a row but didn't boost his technical content in time for the Olympics). Accordingly, this explains why Yuzuru is so desperate to boost his technical content early on and why he insists on competing when he's not 100%
It's all a crazy theory that I was discussing over Thanksgiving and who knows what Yuzuru is thinking, but seeing the desperation in his eyes makes me feel like there's something bigger to him than the immediate media attention/pressure.
