Sheryl Sandberg is an author, activist, philanthropist and Chief Operating Officer of Facebook.

On May 1st this year, while Sandberg and her husband, Yahoo! executive Dave Goldberg, were holidaying in Mexico, her world was rocked.

Goldberg passed away as a result of head injuries suffered after falling off a treadmill.

This New Year, no doubt a very different one for Sandberg and her family, her resolution is not about fitness, food or giving up a long-held vice.
