The human being is in constant building, and all the people with whom we associate contribute in some way to our growth, our evolution, is not only the "good" people, those who remain on our side and the people in our midst today. No, no. All people interfere, so those who now keep only in memories and in no doubt of shadow memories helped us to become what we are. That's why they also owe our gratitude.

Your whole post was beautiful but this last paragraph is a gold standard concept! Growth can/does happen from both the good and bad. While not fun to go through, we have to appreciate those harsh lessons too. :)
