Stop telling us we need to "enjoy our high school years" if that's what we're trying to do, please.
Hey, I get it. I volunteered the summer after my sophomore year of high school (before I had any idea that I wanted to be a physician). It was thrilling and exciting, and I loved it.
But you just gotta branch out and stay well-rounded. It's too early to be so focused on your career. There's nothing wrong with being passionate about your interests, we're just advising to keep all your options open, make sure you don't miss out on life.
And what I meant was, very few of us currently listen to podcasts - some med students may, but I'm pretty sure most residents/fellows/attendings don't (nor do they have time to). I was on the Internet back in high school - I first got online in 1994 - and of course I've always been hungry for knowledge, so of course I read up on everything that interested me. I didn't know I wanted to become a surgeon until college, but although I'd read up on surgical/medical topics and be fascinated, I certainly made sure not to neglect anything else of importance.
Remember, it's a marathon, not a sprint. If you're going to go into Cardiothoracic Surgery, that's at least 17+ years away before you're all said and done. (16+ if you go through a 3+3 integrated training program, and 14+ if you go through a 6-year BS/MD program as well.)
Because none of us highly-motivated, dedicated, passionate go-getters ever look back and wish we had started studying earlier, or had taken more credits in college, or had joined one additional pre-med club. We do, however, regret not taking up that particular hobby, or catching up with family/friends, or taking the opportunity to travel, learn a new language, etc. As I always tell people who are gung-ho in college, you don't want to miss out on the wealth of opportunities presented to you - things that you might never get to experience ever again. And no one looks back and remembers what they learned in their second semester of physics, or what was on the physiology midterm, or how many times you managed to get an A- instead of a B+. You look back and fondly remember the friends you made, the life-altering experiences you had, and the growth and maturity that you went through as you became an adult.
That's the end of my little speech. Best of luck to you.
