God builds mosaics out of the pieces you thought were trash.

Broken pieces have a use that is not obvious while you are holding them. The parts of your history you would rather leave out, the failures and the wasted stretches, are what let you sit with someone standing in the same place. That is not a reason the bad thing happened. It is what can be made out of it afterwards.

Take the part of your story you usually skip and consider who it might be useful to. If it is still too raw to say out loud, leave it, since the point is that nothing is being thrown away rather than that you owe anyone the telling.
