5. çalışmağın zəkadan daha vacib olduğunu müdafiə edən,haqlı da olan professor. gəncliyində princetonda phd imtahanına o qədər də ciddi hazırlaşmır və nəticəsi:

" I was still largely in a state of shock—this was the first time I had performed poorly on an exam that I was genuinely interested in performing well in. But it served as an important wake-up call and a turning point in my career. I began to take my classes and studying more seriously. I listened more to my fellow students and other faculty, and I cut back on my gaming. I worked particularly hard on all of the problems that my advisor gave me, in the hopes of finally impressing him."

başarmaq üçün gizli formul yoxdur yəni, azacıq təmbəllik bütün karyeranı məhv edə bilər, çalışmaq lazımdır.
