While I can't speak on everyone's behalf, I can speak on my own. My sole motivation is to reach my maximum potential at anything I choose to do. For this reason, I had no need to give meaning to perform better. My meaning was to perform at my best. (no I don't bring other people down so that I can be best, I always help people. I teach them etc. I want them to do well too. My ideal world is one where everyone uses their full potential to advance human society.) Anyway, so because of this adding a theme was really just to make myself seem less superficial to admissions committee. As I repeat my story it's become very natural for me and I come off as very authentic but I personally couldn't care less deep down. Will this make me a more attractive candidate? Without a doubt. Adding a theme gives off authenticity, ambition, passion, and positive vibes to your interviewer. Saying that this doesn't help unless it made you more productive is utter nonsense. People want a story because we'd all like to be optimistic about the world and believe that jewels exist out there.There is nothing wrong with having several interests that are seemingly unconnected to medicine. Does the mere act of weaving activities together make you look more attractive? Probably not. The reason why other posters in the past and I have said that it is good to have a theme and some connection between activities is because 1) you will perform better overall at those endeavours because they are tied to what you love to do (i.e. volunteer with special olympics instead of stocking pantries if OP's hobby is PL) and 2) be able to go in-depth about your passions from multiple perspectives (volunteer, research etc all focused on nutrition, for example) and leave a strong memory/impression of who YOU are. Synthesizing a connection to look good negates the benefits aforementioned because your lack of enthusiasm and passion won't help you perform better in those activities and you will have a very difficult time selling why you did what you did in the interview. In short, there is no bonus just because two activities are linked; rather, it is the intangibles associated with having a theme that indirectly helps an applicant.
