Agency is the feeling of being in control of your own behavior and decisions. It's the feeling that you have control over what you do and how you act. Agency is different than just having the ability to make choices. Agency happens when you feel like the choices you make really matter and that you can make the right decision for yourself. For example, if you want to go to the park but your friends want to go to the movies, agency is having the confidence to make the decision that's best for you instead of following what everyone else wants to do.
