Yes!
  I believe there is so much power in positivity, whether it be when interacting with my students, staff, or colleagues.  I continually read up on positive psychology and how it can affect a person.  One summer, when working at an educational and life skills camp, I learned that using positivity before exams and providing your students with a catch phrase to say before taking tests will help boost confidence and performance on the test.  With my first grade students, I always said, "It's time for a test!" All the students would then reply in a whisper, "YES!"  It was so nice to hear them say "Yes" when typically you hear grumbling and complaining! I love the power of Yes!
