One of the most life altering essays I’ve ever read is Montaigne’s To Philosophize Is To Die (https://hyperessays.net/essays/to-philosophize-is-to-learn-t...) where he lays out the principle of memento mori (“remember to die”). Fear of death is often very debilitating, and a topic we all like to avoid but we all have to deal with it, sooner or later. The sooner you accept it, the freer (and happier) you’ll feel.
