I'm Confused.... Why are people so hard on each other???

Life is tough. If one is born with a silver spoon it's not a guarantee of life satisfaction. There's long lists of goofy well off people doing goofy things. If one is born into a world of nothing it's not a guarantee of life going nowhere. We are where we are and much of where we go is up to ourselves.
I am not happy or satisfied in having survived a brain injury but there also lies no guarantee of how far I will go or how little my health will improve. Like salmon working to spawn we are here to swim upstream the best that we can do. Maybe some people do live like fish in an aquarium, being fed and being watched swimming the tank for life. But we are designed to do what we can with whatever we have.
One of the basic tenets of life is how growth comes through being nurtured.
Buddhism teaches a great deal about compassion and I think that it is a very important insight. To allow a plant to grow to fruition and to do what it was designed to do we plant the seed. We tend, water, feed and trim when necessary. We cultivate with care giving it what it needs. Just like we do with our children, pets and other things of value.
But our care and compassion often stops there. In seeing the value of compassion why do we begin to lose compassion for ourselves and for others? And for us to grow to fruition, what if we don't begin by nurturing ourselves so that it may feed others with the fruit of compassion?
Many of us who have survived TBI are quick to anger. Just as the weather changes, my anger arises too as sometimes violent. And just as how the weather changes from a storm to sunshine, I too weather the storm and wait for a better day. Imagine if I cultivated the anger? (there were times I did)
We're surrounded by angry and non-compassionate people. And it is built through ignorance. Not knowing. Not stupid, unknowing.
I am thankful that my injury has helped remove me from much of the ongoing world. People are argumentative everywhere. Husbands and wives, people at work, all of politics. Beginning with self compassion and also working to separate ourselves from the ongoing rush of stress coming through all the faces that surround us, building self compassion, helps enable us to enter the position of helpfulness. For ourselves and for others.
It's the fruition of the well cared for and nurtured plant that will produce or radiate great fruit and beauty.
