Freedom and happiness come from understanding - and working with - our limits. Begin at once a program of self-mastery. Stick with your purpose. Do not seek external approval. Do not worry about anything outside of your control. The only things you command are your thoughts and actions. We choose our response. Stop aspiring to be anyone other than your own best self: for that does fall within your control.
EpictetusIn theory there is nothing to hinder our following what we are taught;but in life there are many things to draw us aside.
EpictetusWhen we blather about trivial things, we ourselves become trivial, for our attention gets taken up with trivialities. You become what you give your attention to.
