balance

/ˈbæləns/noun

A condition where different forces are evenly matched, so nothing tips one way or the other.

Example sentence

“She tries to keep a healthy balance between work and family life.”

Two idioms carry it: "strike a balance" between competing demands, and "hang in the balance" when an outcome is undecided.
