My therapist: Look at nature. Look at flowers. We never walk into our garden and say "Oh wouldn't that flower be so much more pretty if it were taller? Or red instead of pink?" No, we don't. Because nature was created perfect just as it is. And so are we. We are part of nature, we are how we're meant to be, we are perfect just as we are.
Be happy for no reason, like a child. If you are happy for a reason, you’re in trouble, because that reason can be taken from you.
