“Some things are in my control and others are not” – I have known this concept for what feels like forever through the Serenity Prayer.

For the first time I have paid more attention to the “things I can change” aspect rather than the things I cannot. I think it is because I heard it in different words (Stoic philosopher, Epictetus), as above: “Some things are in my control and others are not” that opened my eyes. My focus up to now has mostly been on acceptance of the things out of my control. I still think that is valid and useful.
Now I can see more clearly that I have the ability and the right to be assertive around the issues where I do have control. If my motives are virtuous then I need not worry about the opinions of others. By virtuous I mean wise. The main difference in my thinking is not being concerned what others think. A liberating thought!
