The One-Word Mantra
When your moment in the spotlight comes (high-stakes proposal, important interview, big presentation) it's important to be intentional about using your best communication skills. But over-thinking it can cause self-consciousness and brainfreeze. What's the happy medium? The One-Word Mantra. Instead of giving yourself a list of things to concentrate on, choose a single word that sums up what you want to accomplish ("Relax" "Connect" "Energize").
The February/March 2009 issue of Scientific American Mind, quotes studies that show that athletes who give themselves detailed instructions ("keep ski tips high" and "keep body streamlined" for a ski jumper, for example) are more likely to choke under pressure than those athletes who rely on a single word (such as "smooth").
So, while it's a mistake to give NO attention to your communication style, don't burden yourself with too many instructions. "Simplify."
