Here's a way to twist your newly minted 2010 brain.
Try a day without saying no. Try not to start a sentence with no. Try to not interrupt someone by saying no.
Try to consciously say "yes" in no's place. That's really for the gifted!
But if you can't manage a yes - then see if you can spend a day agreeing with the ideas and opinions presented and build on them instead of pointing out the holes (shore them up instead of tearing them down), you'll find a lot more folks saying yes to you well past the day spent in a no zone!
