As you make your bed so you must lie on it.

Meaning: Your choices about how you arrange your life will directly determine the comfort or discomfort you experience living it.

Example: “You bought the car without checking it; you've made your bed, now lie in it.”

Origin: Recorded in English from about 1590, and related to a 15th-century French proverb: as one makes one's bed, so one finds it. George Herbert included it in his collection of 1640. The image is literal: whoever makes up a bed badly still has to sleep in it. It means accepting the consequences of your own choices.
