Sincere forgiveness isn't colored with expectations that the other person apologize or change. Don't worry whether or not they finally understand you. Love them and release them. Life feeds back truth to people in its own way and time.
Realize that now, in this moment of time, you are creating. You are creating your next moment. That is what's real.
Appreciation is like looking through a wide-angle lens that lets you see the entire forest, not just the one tree limb you walked up on.
We are one big family of people, trying to make our way through the unfolding puzzle of life.
