(My personal favorites: Hanging fairy lights, baking an apple pie, pick flowers, go to a cafe and be okay at some point.)
Hold on to the ones who cheer for you. And soak up some of their happiness. Laugh. It's rewarding.
Remember there are two kinds of diseases we can spread without getting sick. One. The disease of sadness. Two. The disease of happiness. It's up to you which one you decide to spread to the world. :)
