No matter how good you feel about it, do not boast, act on or go to press about a deal you just made (business, employment or otherwise) until the first check goes through. I learned this in Hollywood and continue to stand behind it as I make deals or watch deals unfold around me. You can never completely guarantee a deal will go through until it actually goes through. You can make a serious fool out of yourself by jumping the gun, making public announcements or spending money you don’t have. Better to keep your mouth shut and fingers crossed until fiction becomes fact.
