金字塔原理：好的逻辑树需同时满足MECE和80/20原则，Good issue trees meet MECE and 80/20 rule requirements。 1、问题拆分时，各子问题之间要相互独立，Content of Statements does not overlap。 2、尽量穷尽所有的可能性，避免有所遗漏，Together, statements answer the question or fully describe the idea on the level immediately above。 3、效率不等于效能，子问题拆分完成后，要进行重要性排序，投入精力去解决那些高价值的问题，Time and effort to structure problem。 不学无以长智，不思无以精进，转发分享~
