My personal favorite is the admonition to actually get sleep. Very important, sleep. It made all the difference in my own college career - my grades rose amazingly as soon as I swore off pulling all-nighters. One of my prof.s used to say, "A project designed at 2:00 a.m. should only be critiqued at 2:00 a.m."... and then he refused to show up at that hour. Seriously, what looks like a good idea when you're all sleep-deprived is usually not a good idea. The companion advice is: Don't Draw Drunk.
Friends Don't Let Friends Draw Drunk - and wouldn't that make a great bumper sticker?
The applications of this architectural wisdom to theater is pretty obvious.
The Nightmare by Henry Fuseli (public domain pic). What the painter MEANT to call this work,
obviously, was The 2:00 a.m. Design Idea. Equally obviously, the swooning character is the sleepy designer.
So get your sleep.
Yes, the deadline is unforgiving, but you'll be so much more efficient and make so many fewer bone-headed mistakes (especially with dangerous tools) that any hours "lost" to sleep will repay themselves many-fold. I promise.
