Marilynne Robinson said this quote
“ My point in mentioning this is only to say that people who feel any sort of regret where you are concerned will suppose you are angry, and they will see anger in what you do, even if you're just quietly going about a life of your own choosing. They make you doubt yourself, which, depending on cases, can be a severe distraction and a waste of time. This is a thing I wish I had understood much earlier than I did. ”
