The phrase "less is a bore" implies that simplicity can be beautiful and effective. However, it's important to recognize that there are situations where more is better. For example, when it comes to knowledge or experiences, "more is a bore" does not apply. The more we explore, learn and experience, the richer our lives become. Another antonym for "less is a bore" could be "more is creativity." Sometimes, creativity requires excess and abundance to truly shine. In art, music, and literature, the great works often overflow with intricacy, complexity, and detail. Ultimately, it's not about choosing one extreme over the other, but finding the right balance that fits the context.
