etymonline
outlook (n.)
"mental view or survey," 1742, from out- + look (v.). The meaning "prospect for the future" is attested from 1851. Earliest sense was "a place from which an observer looks out or watches anything" (1660s). The literal sense of "vigilant watch, act or practice of looking out" (1815) is rare; look-out being used instead for this.
