I do not believe is fate, destiny or that sort of thing.
To me, the fact that many people suffer is due to so many of us being ignorant, uncaring, mistaken, clumsy or callous. There are so many unintended sufferings, and many that were caused by the best of intentions.
I think that we are learning more about how people work, and so less of the unintended suffering will occur, but it isn't changing overnight, and many of us have to limp through life.
I believe we don't have to do this alone. I also believe we can be stronger than we rthink.
