I agree with the "can you back it up" angle... I had the same question as you: I want to go into primary care... and I was afraid my secondaries would sound too flowery if I mentioned it. But, I grew up in a tiny town, worked and volunteered with primary care docs... so it's not coming out of left field, ya know? If all my clinical experience had come from a plastic surgeon's office in Beverly Hills, my essays would definitely be a red flag. Stick to your truth, regardless of what it is; it'll keep you out of trouble.
