Apple CEO Tim Cook told an audience on Tuesday how he realized late in life that "the reason we are all here is to help somebody else."

Cook's remarks came at the end of an interview with Salesforce CEO Marc Benioff on stage at the annual Dreamforce mega-conference, where the two had been discussing Apple's corporate values - especially around innovation, user privacy, and environmental stewardship.

Benioff asked Cook: "When you think about yourself, you know, what is your highest value?"

Cook replied with a story about a "revelation" he had that came later in his life, in his "upper 30s."

"At some point, you recognize the reason we are all here is to help somebody else - that that is the sole reason we are here. And once you get that in your head, as it turns out, life gets so much simpler," Cook said, in part. You can read his full answer below.

He said that with this framing in mind, "you can take a lot of decisions that can be very complex, and you can kind of make them pretty simple," he said.
