Overwhelm negativity with joy
A lot of folks believe that everything is energy, positive or negative. On December 10th, no matter what people choose to do, I would like everyone to keep their personal energy as positive as possible, for the whole day. If a negative feeling or thought comes up, dismiss it for a more positive one. Everyone on the planet can do this for some part of the day, if not the whole day, and I see no way that it can cause any harm.
