I don’t think that love is the only thing that matters. My favourite version of the meaning of life is what Viktor Frankl wrote on the topic. He says there are three sources of meaning: love (for humans and for experiences, like a sunset), purposeful work (what you’re trying to do in and for the world), and the courage you find in the face of difficulty. It’s not just about sitting around loving each other; the way you respond to unavoidable suffering is also a source of meaning.
