McDonald’s CEO Chris Kempczinski has some career guidance to share, provided you have “thick skin.”

In a video he posted on Instagram on Dec. 10, titled “Tough Love with the McDonald’s CEO,” Kempczinski revealed the professional advice he would tell people “if I wasn’t afraid to hurt your feelings.”

That advice is, “Nobody cares about your career as much as you do,” he said.

Even if you have a great boss or mentor, it’s rare to have someone “who’s looking out for you, who’s going to make sure that you get that opportunity,” Kempczinski says.

Don’t wait for someone to shepherd you through your career, he says: “You’ve got to own it, you’ve got to make things happen for yourself.”
