每日原则：你没有时间全面检视每个人的想法，因此要明智选择具有可信度的人。

Generally speaking, it’s best to choose three believable people who care a lot about achieving the best outcome and who are willing to openly disagree with each other and have their reasoning probed. Of course the number three isn’t set in stone; the group could be larger or smaller. Its ideal size depends on the amount of time available, how important the decision is, how objectively you can assess your own and others' decision-making abilities, and how important it is to have a lot of people understand the reasoning behind the decision.
