Let’s talk about some of the exceptional people you named in your speech. Ernest Hemingway used his shotgun to blow his brains out. Sylvia Plath was 30 when she stuck her head in a gas oven. Billie Holiday died of acute alcoholism after years of drug abuse. Van Gogh shot himself in a wheat field right after finishing a painting.
Normalizing does not doom you to mediocrity. It allows you to live long enough to do your best work.
