Experience is a brutal teacher but you learn. My God do you learn. C.S. Lewis
Lewis is so right. The things that teach us the most are usually uncomfortable and sometimes outright painful. We learn so much from those lessons. The things that I regret the most and remember the most have been painful lessons. They changed me. Usually for the better.
Frequently those experiences had to do with hurting other people. The result hurt me. Maybe even more than the person involved. The trick is to not make the same mistake again. The important thing is that we learn from it. It is sad when we don’t learn.
