I created Facebook because my friends and I wanted a way to connect with others at Harvard, not because I thought it would become a company.

I made a significant mistake by not investing in Facebook when I had the chance, which taught me to recognize exceptional founders without overanalyzing.

I started a couple of startups and then joined Facebook before leaving to start Mystery Science with Doug.

I started my first company out of my dorm room at Stanford, aiming to help students get jobs at banks and consulting firms, but it ultimately didn't work out because no one was using LinkedIn at the time.

After selling PayPal to eBay in October 2002, I recognized that the consumer internet was just beginning, contrary to the belief that it was over, and I decided to pursue the LinkedIn idea.

I started Facebook at 19, knowing nothing about business, and didn't even realize I was starting a company.

I initially built Facebook for myself as a college student, but I quickly realized its potential to serve a broader audience beyond just my university.

I started Facebook while I was supposed to be studying, but I was more passionate about building something meaningful.

The growth and user engagement on Facebook excited me, even though I wasn't a big user myself; the metrics showed it was gaining traction quickly.
