We are not though. No one out us here, we are just chemistry replicating itself in more and more complex ways as time goes on. The universe does not care about you, in fact it doesn't care about anything. If everything dissapears tomorrow, nothing would remain and no one would care. But you do, we do. Go make your own purpose, and for the sake or practicality, pursue your own purposes in ways that don't stop others from pursuing theirs. Cooperation is a good tool even if your only goal were to be your own happiness.

So find something that feels good. Something fulfulling, maybe something to sustain yourself while you pursue other sources of fulfillment, do whatever.

When you die, you won't care. You only care while you live, so make of life what you want from it.
