I was under the impression the PS was about why you want to be a doctor and I thought all the reasons cited above were genuine reasons for taking this path. So why are you guys suggesting we not write about them? I can't imagine what other reason there could be (except for the people who are in it to make money).
A single anecdote, written thoughtfully and with sincere intentions, is very different than a trite statement thrown in as an afterthought. Many of the PSs I read sound like someone decided to talk about their sick grandmother because they think it will add an air of seriousness to their PS, not because their grandmother's illness actually motivated them to enter medicine. Be honest, but show exactly what your path was. Some people have said "It was this situation that made me realize I wanted to go into medicine," and I'm skeptical that one single situation alone would motivate an entire career. If you back up and beef it up with other experiences, coinciding with your interests, it sounds much more plausible.
Also, showing is better than telling. It's along the lines of "a picture is worth a thousand words." Having DONE something is much more valuable than just talking about doing something. Not only that, but if you can make your point by telling a story that carries that point, it's better than just saying it. A few of the well-written PSs I've read have used stories that show their progression from ignorance/dislike to understanding/appreciation.
if it isn't about serving the underserved - if you want to serve the underserved, and you're going to talk about it, you should have something to back this up. Have you done it already? learned their language? taken steps to work with that culture/social group?
if it isn't about social policy - have you been active with your school's student organizations that deal with social policy? interned with a legislator? at least written letters/editorials/articles about social policy?
if it isn't about your own personal illness/condition - was it a serious condition? did it actually change your perspective, or does it just make a convenient way for you to make it sound like it did?
if it isn't about a dream - this one is tenuous at best. I dream of driving F1 cars and Lamborghinis.
if it isn't about knowing what kind of medicine attracts you - have you shadowed a physician in each possible field? Mentioning your possible interests is okay, but don't say that you're going to be a pediatric reconstructive surgeon specializing in finger amputations.
if it isn't about volunteering in a nursing home/hospital/ER and how that felt - at least make it
interesting though. The 500th story about an interesting conversation you had with a patient is going to make your PS sound very run-of-the-mill.
If you answered "no" to one of the questions pertaining to your interest, then you probably shouldn't be talking about it. You need substance to back it up.
