That no matter what, everybody deserves a right to a happy, healthy, fulfilled life. (Well, not murderers so much), and that anything and anybody who tries to get int he way of that in these the United States, should be reprimanded. By somebody.
That said, we each as individuals can mostly only do so much. We can try to improve the world right around us as best we can and if we are particularly energetic or motivated we can join with others to try to do more. But, really, even that can only do so much so fast.
As with everything in life when it comes down to it, you can only control you. So speak out when you can, live honestly and joyfully and spread that honesty and joy. And take care of yourself.
Watch what you eat, get some exercise, and get out with other people, because living a life alone is no way to live. I am sure, though I’m not going to look it up right now. that people who spend time with other people are happier people who live longer lives.
So those are the things you need to do to live a life that is long and fulfilling and joyful. Because it’s hard to be joyful when you are bitter and don’t feel well. And as you age it seems like those things can go hand in hand.
