With a little preparation you, too, can be a genius. Geniuses are not that different from the way you naturally are. Instead of winging it at the next party you attend, decide what you’ll say in advance, and stick to it. You’ll want to have a solution to war and world poverty, or a new form of clean energy, nothing too outlandish. You’ll want to speak in a clear reasonable tone and a quiet voice; geniuses don’t need to grab attention.
