The point of no return is the point beyond which one must continue on his or her current course of action because turning back is physically impossible, prohibitively expensive or dangerous. A particular irreversible action (e.g., setting off an explosion or signing a contract) can be a point of no return, but the point of no return can also be a calculated point during a continuous action (such as in aviation).

“All our Concord waters have two colors at least; one when viewed at a distance, and another, more proper, close at hand.... Walden is blue at one time and green at another, even from the same point of view. Lying between the earth and the heavens, it partakes of the color of both.”
—Henry David Thoreau (1817–1862)
“Retirement requires the invention of a new hedonism, not a return to the hedonism of youth.”
