You are going to spend at least 4 years or more in graduate school, and around 3-5 years in a postdoc position. That’s a big chunk of your life, so apart from doing experiments, writing papers or your thesis and maybe doing some teaching, what else are you doing?
To paraphrase one of my favorite books (So What Are You Going to Do With That?: A Guide for M.A.’s and Ph.D’s Seeking Careers Outside the Academy by Susan Basalla and Maggie Debelius), what will you have to show for yourself besides teaching and research at the end of it all? For most people, the answer is “probably not much”. But what Basalla, Debelius and I suggest is that it would be very beneficial for you to actively pursue other interests or hobbies while in grad school or doing a post doc.
