A day before New Year, Facebook founder and CEO Mark Zuckerberg wrote a public post on Facebook asking for ideas for his "personal challenge" or New Year's resolution for the year.

Zuckerberg's post immediately went viral; as of writing, it has more than 3,800 shares, more than 144,000 likes, and almost 58,000 comments.

In the past, Zuckerberg's New Year's resolution included writing a "Thank you" note to someone every day, learning to speak Mandarin, meeting someone who does not work for him, wearing a tie and going vegetarian.

He has received different suggestions such as planting a tree for every new user that signed up for the social networking site, running a mile every day, and doing menial tasks per week, among others.

On Saturday, he finally picked the best idea and probably the most doable to him.

"My challenge for 2015 is to read a new book every other week -- with an emphasis on learning about different cultures, beliefs, histories and technologies," he wrote.

He also invited other Facebook users to read along with him by following him in the Facebook Page, A Year of Books.

His picked The End of Power by Moises Naim as his first book.

"It's a book that explores how the world is shifting to give individual people more power that was traditionally only held by large governments, militaries, and other organizations. The trend towards giving people more power is one I believe in deeply, and I'm looking forward to reading this book and exploring this in more detail," he wrote.

Zuckerberg has not announced yet his next books to read, so his followers will always need to check his page for updates. However, CNN's Jay Parini listed some books that he would like the CEO to read as they are fit for busy people. The top 5 list includes the Adventures of Huckleberry Finn by Mark Twain, The Death of Ivan Ilyich by Leo Tolstoy, July's People by Nadine Gordimer, Walden by Henry David Thoreau, and Things Fall Apart by Chinua Achebe.
