On any journey, things may happen that will alter your plan. A breakdown that delays your arrival, a rerouting via a new route, are all possibilities.
While these may be stressful at times, it helps to balance that view with the opportunity given to you. An opportunity to slow down, to rethink, to learn new ways of doing things, to get to know new people, or to get to know yourself better.
When viewed with a balanced perspective, maybe the detour can be a lesson, in more ways than one.
