This has been my experience as well.

I consider myself a pragmatic optimist. I assume the best intentions in those around me, give forgiveness for human error and tendencies, and when someone gives me cause to do so I pragmatically adjust my expectations of them and their actions.

I also assume that, as long as I am trying to do the next right thing in each situation I find myself in, most of those situations will resolve in a positive outcome. Even if others involved are not committed to the same path.

I found much more success and happiness with this philosophy or approach to life.
