"Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy."- Thich Nhat Hanh
Insight: Scientific studies show that "self-perception theory" - acting "as if" one feels something will result in that feeling - is actually true.
Insight: If you don't feel like being nice, act like a nice person would, you'll become a nicer person and feel better about it.
Principle: Fake it until you feel it.
