Premed,
First, here is your disclaimer:
1. I am not a doctor.
2. I have not even applied to any medical schools. (Yet.)
3. My GPA is lower than yours. (In my own defense I've got a lot of undergrad to go.)
4. I am 22, so I may very well have no idea what I'm talking about.
Now that that's out of the way, here is my message:
A few months ago I posted here with a somewhat similar message "My numbers suck but I've got it in my blood and I'll do anything." The standard line is, yes, it's in your blood, good luck. Racergirl boosted my spirits as well with her personal story, which has a fabulous "ending" (as if a medical life's story ever has an "ending", as opposed to a long stream of learning and discovery.)
To get personal, I grew up being somewhat discouraged from "reaching high." After digging through some repressed memories, I discovered that when I was a youngster (a *real* youngster, unlike the proto-youngster I remain as) I used to have a lot of stuffed animals. I talked to them every day. But eventually my mother had to throw them all away. Why? I cut them all open. Operated on them. Convinced myself they were sick. Probably because they were unresponsive and had oral temps of 25 C. (yuk yuk yuk)
Back to my point: Remembering that I cut up those stuffed animals has brought me tremendous joy as I look down the long, long road ahead of me. It convinces me that it *is* in my blood. I don't want a BMW, or a McMansion, or a horde of secretaries offering to freshen my coffee. I want to put my hands on a sick person and find their sick and kill it and let them walk away and live their lives. I don't see any other thing worth my time in this world.
That's how I know that if I want to, I will get in. My resolve is fueled by the fact that it is in my blood. And that gets to the point of my reply to you: Nothing in this world should matter except what you feel your calling is. Even if you've exhausted everything and no adcom will take you, move to equatorial Africa with your science knowledge and I guarantee you you will heal the sick. Maybe this doesn't appeal to you: If it doesn't, you won't be a good doctor.
Recently I've taken a job in a hospital and I've already seen, in three weeks, good doctors and bad doctors. Those with fire in their eyes and those with golf in their hips. The ones with fire wouldn't trade it for the world, and failure was never an option.
If you want to heal sick people, you will. If you want a BMW, you will have one. If you want to fail, you will fail fantastically. I don't want to Yoda you; but don't let anyone tell you anything. Not this board, not an academic advisor, hell, not even an adcom. Fulfill your life's mission and when death takes you, you will smile.
Good luck.
