If you need a New Year's resolution role model, check Facebook.

This week Facebook CEO Mark Zuckerberg showed off his artificially intelligent assistant, Jarvis,which he spent 2016 building from scratch as one of his New Year's resolutions.

But that's hardly the first impressive accomplishment that has come from Zuckerberg, who is known for setting and tackling ambitious and unpredictable New Year's resolutions.

While he hasn't told us what's in store for 2017 yet, here's a look back at the various resolutions the social media entrepreneur has completed:

Reading More Books

Last year, Zuckerberg committed to reading a new book every other week and announced each title on the "A Year of Books" Facebook page, where he encouraged other Facebook users to join him.

Writing One Thank You Note Per Day

The billionaire admitted the daily gratitude challenge in 2014 was surprisingly a tough one.

"There are people who see the beauty of things," he said at a Facebook Town Hall meeting that year. "Then there are people who see things and want to make them better, and I tend to be the latter."

Meet Someone New Every Day

Bad news: Your best odds for being Mark Zuckerberg's new friend may have been in 2013. That year, Zuckerberg made it a resolution to meet someone new - who doesn't work at Facebook - every day.

That meant having a conversation, not a simple passing "hello" or handshake.

Zuckerberg ditched his trademark t-shirts and hoodies in 2009 and wore a tie every day to work - a markedly different look for the laid-back CEO. While he gave it an admirable effort for the year, this resolution clearly didn't stick, as Zuck went back to his classic uniform in the following years.
