Just a reminder: grad school is for 4-6 years. Sunny afternoons are far, far shorter. If it’s been a while since the sun was out, and it’s a sunny afternoon, get thee outdoors for a little while, even if it’s just for a short walk. You really will feel better.
(Short and sane posts are intended to offer quick bursts of motivation, inspiration, or commentary on various aspects of graduate student life and work to help keep us all sane in this otherwise utterly chaotic life we’re living.)
