The bags under your eyes from editing video until 1:30am
The crack in your foot from that move you keep rehearsing because you keep thinking "oh my goodness if I fall..."
The trips to the store for another prop you need...
but really! it's magical, I swear! I've uploaded some photos by the wonderful Adam Jason from our most recent rehearsals, feel free to browse and check out Adam's site as well! Now, I'm off to sleep...for about 10 minutes. That's showbiz, kids :)
