Nihilism is the belief that life has no inherent meaning or purpose, suggesting that the universe is indifferent and nothing holds ultimate value. In other words, there are no universal truths and everything is subjective. Optimistic nihilism takes this a step further, not as a reason to feel hopeless but as an opportunity. Without predefined rules or expectations, we are free to create our own purpose and meaning. It’s about embracing the idea that while life may not come with built-in meaning, we have the power to define what matters to us.
