My question is, why not be happy? Why berate yourself or criticize yourself over being human? What have you done that was so wrong to think that you deserve suffering? None of us are perfect. Guilt, misery and self-pity do nothing to help us, or the world around us. When we realize we deserve happiness, and that happiness is a choice we can make at literally any time we wish, anywhere, then it's easy to find happiness in our lives and then spread it to others, without refrain, expectation or jealousy. It's all an inside job.
