A few things I've learned so far:
You will learn all the roads to, from, and surrounding the studio VERY quickly:
You will run LOTS of errands including but not limited to grocery shopping, prop shopping, prop shopping, prop shopping, office supply shopping and restocking, cleaning, organizing, cleaning some more, and coffee and/or lunch runs/pickups:
You will set up sets, change sets, alter sets, tweak sets, perfect sets:
...and then tear down those sets and start all over... several times:
You will prep and fetch props and anything that might become a prop:
You will hit any and all traffic coming in, through and out of the city:
And at the end of the day you will feel exhausted, drained, and beat but more importantly you will feel happiness, validation, and inspiration and you will gladly set the alarm for some crazy early hour to start all over the very next day.
