The voices in your head are wrong. Don't listen to them. You're not a machine learning model, you're a human being with a stomach that needs coffee.
You don't need to question everything. You just need to question the voices that are telling you to question everything.
But seriously, have you tried ignoring them? It's not that hard, really. Just pretend you're a coffee bean and let the world spin around you.
Or, you know, just get some coffee.
