Don't be a perfectionist, because perfectionists often spend too much time on little differences at the margins at the expense of other big, important things. Be an effective imperfectionist. Solutions that broadly work well (e.g., how people should contact each other in the event of crises) are generally better than highly specialized solutions (e.g., how each person should contact each other in the event of every conceivable crisis).
Ray DalioThe main reason I write the daily observations is because I want to know where I'm wrong. So lots of times if somebody points something out it helps me, and I want to have a diversified bet of uncorrelated bets.
