Focusing on “the comeback” after going through a difficult situation means that getting back to where you were before is at least the baseline, if not the goal. The problem with that is tough times often show us we need to alter our path a bit, or even go in a completely different direction.
It’s easy to want things back to how they were before. We’re familiar with “before” - it’s comfortable. But life isn’t always comfortable. It’s constantly moving forward. And while need to learn from our past, we need to keep moving forward too.
