"By the time I got to work, I had this realization that I didn't have any more goals."26 For the next two months, he assiduously tended to the task of finding for himself a worthy life goal. "I looked at all the crusades people could join, to find out how I could retrain myself." What struck him was that any effort to improve the world was complex. He thought about people who tried to fight malaria or increase food production in poor areas and discovered that led to a complex array of other issues, such as overpopulation and soil erosion. To succeed at any ambitious project, you had to assess all of the intricate ramifications of an action, weigh probabilities, share information, organize people, and more. "Then one day, it just dawned on me--BOOM--that complexity was the fundamental thing," he recalled. "And it just went click. If in some way, you could contribute significantly to the way humans could handle complexity and urgency, that would be universally helpful."27 Such an endeavor would address not just one of the world's problems; it would give people the tools to take on any problem."
