People are always so boring when they band together. You have to be alone to develop all the idiosyncrasies that make a person interesting.

The remark contrasts the flattening effects of group conformity with the creative and psychological space of solitude. Warhol suggests that when people “band together,” they tend to adopt shared tastes, slogans, and social scripts—becoming predictable and, in his word, boring. By contrast, being alone allows quirks, private obsessions, and unconventional habits to grow unchecked, producing the “idiosyncrasies” that make an individual distinctive and compelling. Read in a Warholian key, it also hints at the paradox of modern celebrity and mass culture: crowds manufacture sameness, while the interesting persona is often a carefully cultivated singularity. The line functions as both social critique and advice about cultivating originality.
