You are never going to be perfect. I am never going to be perfect. Perfection is not attainable. Happiness is always transient. Makes you want to give up already. Then, as if life isn't difficult enough, neuroscience reveals our brains are wired from birth toward negative thinking. Negative thinking helps us expect and see danger because we know it's out there, which aids our survival. Unfortunately, negative thinking also makes us miserable; but, we do it so often, we are experts in manufacturing our self created misery. You know this: If you do something often enough, you're going to get really, really good at it. No wonder we are experts when it comes to seeing "the glass is only half full." Our negative circuits are always busy! Why try, right? The answer is, you should try. Life is short. While you are here, you want to enjoy as much of your life as you can.
