Jesslily..
I gave some careful thought to your post before responding. The major issues you raise in your post are about popularity, and the ability for one (anyone I presume, figure skater or not) to adjust schedules based on personal priorities.
I agree that almost anything can be successfully scheduled, if it is truly the top priority. It's simply a matter of what lesser priorities one is willing to give up to pursue the top priority.
I suspect that in Sarah's case, her education became her top priority once the Grand Prize in figure skating was accomplished. I still think the timing (and actuality) of the Grand Prize came as a surprise to her, hence some waffling as she sorted it out.
I also suspect that popularity with skating fans ultimately was a low priority for Sarah, and that's OK. While all of us "want what we want" for these skaters, ultimately they are doing the work, doing the time, spending the money and are free as we all are to make their own decisions without obligation.
To draw a contrast AND a similarity to Sarah, I would speculate about MK's decisions. I suspect the reason she is still competing, staying and playing is NOT because fans "expect it" from her, but because she wants to.
I don't know either of these ladies personally, so these are just my speculations. But my impressions of both are that they are strong, intelligent, and independent minded young women who are making what they feel are the best decisions for themselves. No harm, no foul.
