Casinos are conceived in a way that depletes your decision-making abilities and emotional reserves. Some of it is on purpose. The slot machines, the free alcohol, the amenities crafted so that you never need to look outside the casino walls. But some are side effects. I don’t know if Sheldon Adelson studied the psychology of creativity or emotional well-being, but had he done so, he’d know that by building a world where you never have to go outside, he was building a world designed to curtail them.
