I recently watched a video on being happy. It mentioned that studies report saying: "thank you" at every opportunity increases one's happiness. I've also read, previously, that smiling increases happiness, even if you don't feel particularly happy.

During the video, the narrator began her conclusion with the words: "To get the ball rolling..." This caused me to imagine something called the "happiness ball". It includes such things as: smile allot... whether you feel like it or not. Say thank you as much as possible... and say "please" too. Saying "please" wasn't mentioned in the video. But, hey, it can't hurt... neither can "you're welcome". Offer sincere compliments when the opportunity arises And a bunch of other things.

So what else might be included in the "happiness ball"? All suggestions greatly appreciated!
