We are two days away from Christmas. Why oh why am I not feeling the holiday spirit?! Apparently, I need to take cue from Mike Zuckerberg who is very much in the giving mood.

In 2012, Mark Zuckerberg, the co-founder and chief executive of Facebook, and his wife, Priscilla Chan, donated 18 million shares of the company’s stock to the Silicon Valley Community Foundation.
