I need to pick a specialty already??

So I went into internal medicine to postpone some decision making. I liked both surgery and medicine, but I thought medicine had more options. Either way, I'd be helping make people better (hopefully) so I didn't feel that much pressure. I am loving the CCU so much that I am teaching my non-medical husband to read EKGs. Where are some med students to teach when you want to? I'm on call tomorrow, a Saturday, and I am hoping I have some admissions so I can actually learn some stuff and get to know some of the attendings. When I started this year I was thinking onc, but I love how much effort has gone into everything we do in cardiology. There have been big controlled double-blinded studies and we actually know what strategies are best. Less guessing. Plus, heart disease is so common that I know I could work almost anywhere when I am through. I need to spend some days in the cath lab, but I have a feeling I'll love it. Just to see such fast improvement will be a cool thing.
