A setback can shrink the path without eliminating the destination.

A setback usually reduces your options, lengthens the timeline, or makes the route harder. It does not necessarily touch the destination. Confusing a narrower path with an impossible one is how people abandon things that were still perfectly available.

After a reversal, ask separately what is now harder and what is now impossible. The second list is usually shorter than it feels. Replan the route and keep the destination where it was.
