wait for one's ship to come in

wait for one's ship to come in (waiting around for opportunities instead of going out and making something happen) — выжидать; ждать у моря погоды

The Breast Friends website, for example, features a series of inspirational quotes: "Don't cry over anything that can't cry over you"; "When life hands out lemons, squeeze out a smile"; "Don't wait for your ship to come in… swim out to meet it," and much more of that ilk.
