#1 Best advice i can give you is learn on someone elses dime. Get a job working with another pro haunt for a few yrs and absorb all the inside info you can. While working take notes write down ideas and start amassing an inventory. Get your self deep into your haunt community. Go to the city and get codes. If you can go to college or trade school do it and see what extra things you can take from it (theater arts degree) Most importantly have fun and enjoy your self now there will be days haunting sux and you need those fun times to get you thru. There are far worse things in life than getting paid to abuse teens with a chainsaw
