own man/person, to be one's

own man/person, to be one's

To be in charge of one’s own affairs and actions. This term is very old indeed and may be obsolescent. Chaucer, who often portrayed strong women, used it (Troilus and Criseyde, ca. 1374): “I am myn own woman wel at ese.” A modern equivalent is to do one’s own thing.
