62. Startups Live in a Multidimensional Landscape
Success requires several interdependent variables to be right at the same time.

A startup is not a single good idea but a coordinated solution across market, product, timing, distribution, economics, team, and defensibility. Excellence on one axis does not compensate automatically for failure on another; one badly wrong dimension can move the company far from profit.
Maintain a live map of the major dimensions and the evidence behind each. Test the weakest, most uncertain assumptions early and watch how changing one affects the rest. Respect luck: with so many variables, success may reflect favorable alignment as well as founder skill.
