I "bless" people in public with interesting results...

That is certainly one way to do it. Being in a positive mood and attitude, especially when there are a lot of others around you who are not, has a quick and subtle effect...a whole room of people who are upset about something (say, a tragic news story on TV), will then do something like turn the TV down, stop arguing about the story on TV, and start doing other productive things around the house while slowly getting back into a lighter mood...all because I decided to go into the room, not pay attention to anything going on and just put on my headphones and enjoy the music I am listening.

Real fun results!
