Finny, you are absolutely right about positive wordage.
It really does work. It takes effort to change the habit, but it makes a difference.
At the races, it was SO VERY GRATIFYING to see that in nearly all of the 911 commemoratives there (and there were lots,, the words "Remember" and "Always remember" were used -- one rarely saw the word "forget" with a negative. I was so happy to see so many who understood the power of language and resisted letting their egos be offended by the concept of "pissy little word games."
