Ajay Banga didn’t like the existing decor, so when he took over as World Bank president he gave his grand two-story corner office a makeover. Old-school leather furniture? Gone. Dark lighting that made the space feel like a dungeon? Replaced. And a depressing painting? Swapped out for three framed motivational quotes: “Question everything always,” “Done is better than perfect,” and “Fail harder.” “They are kind of my philosophy of working,” he tells me only moments after my walking in the door.
