Two Vicious Traps

Morgan Housel argues that some of the most dangerous personality traps arise when two admirable traits combine in the wrong way, and these flaws are the hardest to identify and fix. He gives patience plus confidence, which can form stubbornness, and curiosity plus boldness, which can form impulsiveness. Humility plus ambition, he writes, can settle into hidden arrogance, and Walt Disney's brother Roy is cited as the figure who curbed Walt's wild ambition into viable businesses.
