Theory of Relative Happiness-- by NobodyHere

My theory of relative happiness essentially means that
you don't feel good or bad. Just better or worse than before.
This insight opens a new path to happiness:
depress yourself and in the relief following that depression,
you will experience an overwhelming sense of bliss.

I'm still working on the scientific evidence.
