The detour gave you a view the highway never would have.

Being forced off the planned route puts you somewhere nobody chooses on purpose. That place has people, problems and skills the direct path never exposes you to, and you pick them up without meaning to. Years later, the thing that makes you unusual is often whatever you learned during the part you resented. Efficiency and interest are not the same measure.

Take an inventory of what the unplanned stretch actually gave you, specifically. Find the one skill or relationship from it that you still use. Notice that the direct route would not have handed you that, and let it change how you read the next disruption.
