efficacy

"The lives of innovators and social reformers driven by unshakable
efficacy are not easy ones. They are often the objects of derision,
condemnation, and persecution, even though societies eventually
benefit from their persevering efforts. Many people who gain
recognition and fame shape their lives by overcoming seemingly
insurmountable obstacles only to be catapulted to new social realities
over which they have lesser control. Indeed, the annals of the famed
and infamous are strewn with individuals who were both architects and
victims of their destinies." -- A. Bandura, "Exercise of personal and
collective efficacy in changing societies"
