Ruminant,
Please try not to get defensive, I think what most of us are reacting to is your "all or nothing statement".
Personally, I want to be a doctor so badly, and have such a clear vision of my career in my mind that the thought of applying once and giving up just never entered my mind. Either you get in this year or you give it up forever??? I don't want to judge but it just doesn't seem like your committment is that deep.
I've said this before on another thread, but I'll say it again: it is sooo worth it to take the time to develop your application, your life story into something that conveys a coherent "argument" as to why you should be a doctor. Just because med schools only require you to have a bachelors's degree with some cookie cutter ECs to get in doesn't mean you have to stop there... After all was said and done it took me 4 years to amass a meaningful set of experiences that would leave no doubt in the adcoms mind that women's health is what I was put on this earth to do. I won't go into all the boring details, but it involves taking the time... and as a result I've only had to apply once, no heartaches, no rejections, and interviews at all top 10 and 20 schools, and several acceptances. In the end my personal statement wrote itself, but reflected the years of introspection. I'll be 25 when I start, I'll be "below 30" when I get my MD, and I don't think the extra time earning a graduate degree, publishing research, training as an EMT, working in clinics, going abroad etc. has been a "waste of time doing nonsense"... I've been doing what I love
Don't blow off the importance of being unique, as others have said--we all are, but you still have to weave a unique thread through YOUR life.
Medicine is an honor, a priviledge, and an immense undertaking and for that reason admissions committees have to select the best, brightest, and the most COMMITTED!
Take hard look at not just why you WANT to be a doctor, but what have you done to DESERVE the responsibility. How have you gone above and beyond the call of duty?
Remember, you're young, and life is a marathon, not a sprint
