Agency and self-efficacy are deeply intertwined, like the will to act (agency) and the belief that you can succeed (self-efficacy). They reinforce each other in a feedback loop, but they aren’t the same thing.
How They Influence Each Other
Self-Efficacy Fuels Agency
If you believe you can accomplish something, you're more likely to take action .
agency is acting with the belief that one can attain something by committing to it. Agency is a Stoic value, as it encourages one to focus on what is under their control—taking action, self-belief, and commitment—unlike success, which requires something outside of one’s control, mainly recognition from others.
