Over some others since "You have always wanted ".(to be the Monster in a haunt.) Desire can be 90% of any undertaking and can energize and empower you to overcome physical exhaustion to keep you going, doing more because you love doing it and feed off of the customer's reactions, and you better enjoy it all you can since it is "seasonal" (Except in my house The Ravens Grin Inn"-OPEN every night)
Show up for work. Do what you are told to do. Ask how much if any improvising they will allow since you are just beginning they might not want any freelancing on your part until they get to know you better.
Avoid any and all employee dramas, no employer ever needs or wants this.
I do what I do here and really have little clue to what goes on in an October/only haunt as far as "acting" goes, but your exposure to any customer will usually be a very brief thing, just mere seconds...
I am at the complete opposite end of such things talking, storytelling, acting, entertaining, scaring people for the entire time we are open.
I am almost never at a loss for words as far as subject matter/material is concerned . There is So Much I can talk about here, and most people do find most of it interesting.(Or Frightening!)
I have been open almost every night , I have owned this haunted, haunted house for 26 years, a great number of strange, funny, and interesting events have happened here, and still do.
Good Luck pursuing your Dream! It WILL HAPPEN.
