Kevin O’Leary says the Gen Zers who shine the most are the ones who can get the job done—whether they’re in the office or not.

O’Leary, the founder of venture capital investment platform O’Leary Ventures, said young people should focus on “executing” to be successful. The Shark Tank star, who has previously been critical of certain habits by younger people in the workforce, said those who want to succeed should focus on delivering results.

“If you’re a Gen Zer and you can execute, and you can hit your mandate and deliver it on time, you move up and you make more money,” he said in a video last week.

As an example, he cited an employee who started working for him a year-and-a-half ago in the United Arab Emirates. This unnamed employee quickly moved up the ladder because “the kid can execute,” he added.

O’Leary, whose own employees are spread between London, Los Angeles, and Canada, said this ability to “execute” also has little to do with whether an employee is in the office or not.
