Honestly, I wonder whether he'll be able to ever smile wholeheartedly before/unless he wins the 1500m World Champs.
It really says something (impressive!) about his mentality that he just had one of the most insane seasons by a middle/long distance runner ever, and is probably feeling crushed and looking at it as a catastrophe. I really hope he gets the gold before he has to move up in distance from the 1500.
