As I was helping my daughter get a sliver out of her toe, I realized there is a life lesson in slivers. You can leave it in, enduring a small amount of pain for a long time, left there, it could fester and even make you sick after a while.
You can deal with it, likely experiencing a lot more pain for a shorter time, but in the long run get it out and let things heal.
I think we often carry around emotional ‘slivers’ far far longer than physical ones. We could learn a lot from a sliver.
