Reality isn’t the most pleasant of atmospheres, Lieutenant. But we like to think we’re engineered for it. It’s a pretty fine piece of engineering, the kind an engineer can respect. Drag in an obsession and reality can’t tolerate it. Something has to give; if reality goes, your fine piece of engineering is left with nothing to operate on. Nothing it was designed to operate on. So it operates badly. So kick the obsession out; start functioning the way you were designed to function.
Theodore Sturgeon, More Than Human
