Date night outfits!
Even if your date is another graduate, you should attempt to throw off your troglodyte demeanor (labs do often feel like caves, don't they?) and look like a denizen of the real world. So make sure you -- wait, what? You don't have time to date? Research takes up every precious moment of your day? Nonsense! There is time for everything. Here is an easy way to get more time out of your day: retrain yourself to not use the snooze button. The technique seems silly. C'mon, practicing getting out of bed? We're past kindergarten, thank you very much! But it works, because it retrains your subconcious mind, which is what is making those groggy decisions to hit the snooze button half a dozen times. So give this a few tries, and soon you'll find yourself with a little excess time every day. Enough time to date, even.
