Mark Zuckerberg did his first public Q&A session ever on Thursday, taking on a number of interesting questions about him and his company.

The topics that were covered include why users were forced to download the Messenger app, why organic Page reach is decreasing and women in technology. But the young CEO also covered some more mundane topics, such as why he always wears a gray T-shirt.

"I'm in this really lucky position where I get to wake up every day and help serve more than a billion people, and I feel like I'm not doing my job if I spend any of my energy on things that are silly or frivolous about my life, so that way I can dedicate all of my energy towards just building the best products and services," said Zuckerberg at the event.

Zuckerberg also went into his views on the movie about his life, The Social Network, which came out in 2010 and got very positive reviews. Despite the reviews, Zuckerberg said that the movie was generally embellished.

"They made up this whole plotline about how I decided to create Facebook to attract girls. One important piece of context: The woman who I'm married to, who I've been dating for more than 10 years, I've been dating her since before I started Facebook. If I was trying to start Facebook to find more women, that probably wouldn't have gone over too well in my relationship," said the Facebook CEO. "But we had some fun with it. We took the whole company to see it the day it came out. There's this scene in the movie where we're drinking appletinis. No one had ever heard of appletinis before this movie. For awhile, everyone around the office was drinking appletinis, making fun of me in the movie."

Zuckerberg, of course, also talked about more important issues, such as the company's role in business marketing and why there aren't many women in tech. He also went on to talk about Facebook's cool factor and why it doesn't really matter if Facebook is "cool" or not.

"It's an interesting question to me because my goal was never to really make Facebook cool. I am not a cool person. I've never tried to be cool," continued Zuckerberg. "Our model for Facebook has never been to try to make it particularly exciting to use. We just want it to be useful. The services we aspire to be like in the world are these basic things that you rely on that are there."
