You only have power over your own reaction, not those of others, so focus on your own choices today.
Whatever is going on in your life today, focus on how you react and what your instinct is, rather than on what anyone else is saying or doing. You cant control how others react to things and what choices they make, you only have power over yourself. It may be frustrating to know you have no influence, but learn to deal with it and concentrate on yourself.
