This news item from science@CornellVet is about: "You should never do experiments when you're hungry, tired or overworked!" My PI's advice rang in my ears as I looked at evidence of my failed experiment in disbelief. All I had to do was add two solutions to a tube, and I'd somehow screwed it up. Going over my week, I realized I'd skipped lunch three days in a row, I couldn't remember the last time I'd slept a full 8 hours, or when I'd last stepped into the gym. When I started graduate school, I'd sworn I wouldn't become "that student," and yet, here I was. I realized that if my brain felt too fuzzy to add a solution correctly, and messing this up had me blubbering like a three-year-old, I was definitely doing something very wrong.
