Sometimes the bridge burning behind you is simply making backward impossible.

Occasionally the loss of a way back is what finally makes forward possible. As long as retreat is available, part of you keeps considering it, and that consideration takes energy away from the thing in front of you. The closing hurts and it also settles the question.

If a return is no longer possible, stop spending energy on whether it should be. Put the whole of your attention on what is next. Forced commitment is still commitment, and it works the same way.
