For me the big one is letting go of the need to control.....other people, things, politics, the weather. I want to control all of it. So thanks for this post Mike, this comes at a very good time for me.The long version of this concept is the Serenity Prayer. For those who don't know it goes like this:God, grant me the serenity to accept the things I cannot change,the courage to change the things I can, and,the wisdom to know the difference.It seems to be the wisdom part that I lack most often.
