The knowledge that nothing matters, while accurate, gets you nowhere. The planet is dying, the sun is exploding, the universe is cooling, nothing matters. The further back you pull, the more that truth will endure. But when you zoom in on Earth, when you zoom into a family, when you zoom into a human brain and a childhood and an experience, you see all these things that matter.
We have this fleeting chance to participate in an illusion, how is that not better? Knowing the truth can actually save you in those moments; nobody exists on purpose, nobody belongs anywhere, everybody is going to die.
Once you get through that terrifying thresh-hold of accepting that, then every place is the centre of the universe and every moment is the most important moment and everything is the meaning of life.
