It's the Academy Awards tonight, and so far, winners have kept their thanks brief and powerful. Accepting an award's a time when eloquence = less is more. Audiences can easily relate to your being overpowered by emotion, and don't expect a long speech--or list of credits. (Our favorite tonight: The winner who said he'd spend the next year thanking all his personal helpers every day, instead of on the stage tonight.) Even better: Craft something casual, quick and powerful to say...and if emotion takes over, just say "Thank you."
