Facebook founder and CEO Mark Zuckerberg capped off a busy week by getting married to longtime girlfriend Priscilla Chan.

The couple, who met at Harvard and have been together for nine years, tied the knot in a small ceremony at Zuckerberg's house in Palo Alto, Calif.

Chan, 27, has been busy this week too — she graduated from medical school at the University of California, San Francisco on Monday.

Speach of Mark Zuckerberg: No shortcut to success

There are no shortcuts to success– "A lot of building a company or a product like Facebook is just about determination and believing that you can. Everything that's worth doing is actually pretty hard."

Great relationships are the most important thing — "No one ever does anything alone. Great friendships make life fun and meaningful."

Do what you love – "It's a lot easier to focus on challenges that you actually really enjoy doing."

"It's not about a single moment of inspiration or brilliance, it's years and years of practice and hard work … Anything that's really awesome takes a lot of work."
