On the Eve of Medical School

I just uploaded onto facebook photos of my white coat ceremony that happened earlier today. After finishing uploading, I flipped through the photos. I seemed to me that that I looked older and more mature in those photos than the image I have of myself. Maybe it's the short hair, the smartly cut dress, or the (albeit short) white coat. Or maybe it's that in my mind, I know that it's the beginning of a formidable commitment.
