Nvidia Corp CEO Jensen Huang once gave a 14-year-old a surprisingly candid look at his childhood, admitting he was a mischievous, restless kid who loved taking things apart, building things and setting things on fire.

Jensen Huang Wasn’t Exactly a Model Kid

In a 2014 interview with eighth-grader Elijah Rogers of the Dallas International School, Huang was asked whether he already knew at 14 that he wanted to become an engineer.

His answer was anything but conventional.

Huang joked that if he were Rogers’ mother, he probably would not want him hearing too much about what Huang was doing at that age.
