The more you let go of trying to control, the more control you will have.
In life there are situations that do need to be controlled but for those situations that we have no control over (other people) we must let go. Apparently with a little faith life will happen as it should. If you don’t fight it, it will work out.
I think this works especially well when it comes to trying to control others. In my opinion, people are often very limited in their capacity to see outside of themselves. Many times it’s innate or possibly the way they were nurtured. You should expect nothing from others except that they will be who they are (and that you cannot know unless you “know” them completely–but how is that possible when one does not know themselves?)
