Hey there. Orianna here from Fortune.

Gen Z and young millennials might groan at the idea of fetching their boss’s flat white. And who can blame them? Optics matter, and they know that being the person who always grabs the coffee, takes notes, or organizes the lunch (also known as “office housework”) can make you look junior.

But Stephanie Kramer, who has climbed the ranks from Chanel to the corner office at the world’s largest beauty company, L’Oréal, says those small tasks are often where opportunity begins.

“At the beginning of my career, I often credit it with the ability to say yes to the very, very little things,” Kramer, the CHRO of L’Oréal U.S., recently told me in Fortune. “Who’s going to make the copies and going to get the coffee? Me. Who is going to be there early to set up the meeting? Me. Who is going to go watch which door consumers go in to determine what the best bay or window is for Saks Fifth Avenue that we want to have? Me.”

Instead of making you look like the most junior person in the room, the Fortune 500 chief argued that saying yes to those tiny, unglamorous tasks gets you unprecedented access.

“If you’re the one that is going to capture the actions from the meeting and the next steps, and you’re listening and you’re observing that isn’t necessarily a negative,” Kramer said, while adding that it puts you in rooms with leaders, lets you see how they make decisions, and helps you start building relationships at the top.

“Just make sure, when you’re discrediting some of those more small tasks, that you’re not discrediting their value they bring to you and your learning.”

Kramer’s message to young workers? Don’t turn your nose up to the small stuff, because the value will compound over time.

In the end, each yes opened doors to bigger challenges and bigger career opportunities: “There comes a time, where you’re saying yes, and they’re like, who can go abroad and take this very strange project in pre-Olympics China? I was willing to get on a plane, speaking no Chinese, and take those risks.”
