point of no return, n.All

The Point of no return (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the aim of a journey that has stopped being one: the instant you see it has no reason to end.

The Point of no return (n.) came ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠at the eleventh step: "Turn and go back; if I don't turn now I shall never go back" — he pondered for ten steps, and at the eleventh he did not turn.
