Balance. I'm not good at it. You'll hardly ever see me getting around campus via handstand, and not just because it would be uncomfortable and socially unacceptable. While my core strength may fail me (or maybe I have an inner ear problem?), I'm getting better at bringing balance into my life. Between taking science classes and homework, working in a genetics lab, and being an undergrad TA for another biology lab, I get in a lot of science throughout my week. As much as I love science, I have other interests, too, and I like to branch out every once in a while. So what do I do to keep sane in the sea of premeds? Balance! (not literally, of course)
There are students here in every major you could dream of, and while I may bother them every once in a while by talking about my latest science experiments (or more often than that, if I'm being honest), we usually talk about completely unrelated things like, "If we were in High School Musical, which characters do you think we'd be?" or "Do you want to watch this video about mudskippers with me?". (I am very lucky to have a roommate that will watch mudskipper videos with me at any time of day or night).
I also add balance into my life by forcing myself to go to the gym (sometimes) and joining clubs and a sorority. I even try to take some classes outside of the math and science realm (yay distribution requirements!). It's easy to get bogged down in the details of your major when you take classes and do outside work and research, and while that's great, it can also be unbelievably relieving when you take a step back and realize that there are other perspectives and views. While I could (and for the most part, do) look at the world through my biology-major lens, if I only look at the world that way, I'm losing so many other perspectives.
I love taking child development classes. Not only can it be tied to biology, but child development also brings in factors of culture, socio-economic status, and gender identity, among other things. I've also taken classes such as acting (which was an amazingly different experience than all of my science lectures), philosophy (although I have to admit that I'm really, REALLY bad at philosophy), and Spanish!
While I may be a biology major, there's plenty of time to get in all of my major requirements, pre-med requirements, and then have some time left over for fun activities and other classes outside of my major. And not only am I a much more balanced person, but I'm also probably a much happier person for it.
