Advice is a valuable commodity when it comes to learning leadership. But according to Mark Zuckerberg, sometimes listening to yourself is the most important advice.

The Facebook CEO held a town hall-style question and answer session at Mobile World Congress in Barcelona on Mar. 4, where he addressed topics such as his hiring practices, the ideal team size and working with Sheryl Sandberg.

But one of the most insightful moments from the Q&A came when Zuckerberg was asked what advice he had for young people with world-changing ideas. The 30-year-old billionaire said, “The most important thing is to just have faith in yourself and trust yourself. When you’re young, you hear that you don’t have experience to do things, that there are people that have more experience than you. [But] I started Facebook when I was 19.”

“Don’t discount yourself, no matter what you’re doing,” he continued. “Everyone has a unique perspective that they can bring to the world.”
