GIVING IS SELFISH.
When you give, here is what happens.
By being generous, you dump happy hormones throughout your body, you pull yourself away from fight or flight, and into rest and relax, you expand your ability to empathize with others, you gain self-confidence, and reduce the incidence of depression and anxiety.
And right after, you feel like a generous giving badass superhero, and that feels pretty damn good.
GO be a giver.
