Sheryl Sandberg Just Gave Some Brilliant Career Advice. Here It Is in 2 Words [H/T @ChrisPavese] (LINK)

I want you to think about the following question, because it can mean the difference between just getting through the day at work, and doing the best work of your life.  

What's the most important thing you can get done today? 

Sheryl Sandberg recently spoke to Inc. to share some lessons learned over the years. One concept she spoke about really resonated with me. 

It's called:  

Ruthless prioritization. 

"I think the most important thing we've learned as we've grown is that we have to prioritize," said Sandberg. "We talk about it as ruthless prioritization. And by that what we mean is only do the very best of the ideas. Lots of times you have very good ideas. But they're not as good as the most important thing you could be doing. And you have to make the hard choices."

Sheryl Sandberg's post about her late husband Dave Goldberg

Link to: Sheryl Sandberg's Facebook post

A childhood friend of mine who is now a rabbi recently told me that the most powerful one-line prayer he has ever read is: “Let me not die while I am still alive.” I would have never understood that prayer before losing Dave. Now I do. 

I think when tragedy occurs, it presents a choice. You can give in to the void, the emptiness that fills your heart, your lungs, constricts your ability to think or even breathe. Or you can try to find meaning. These past thirty days, I have spent many of my moments lost in that void. And I know that many future moments will be consumed by the vast emptiness as well.  

But when I can, I want to choose life and meaning.

This also reminded me of another post (from a U.S. soldier) about realizing what's important in life: Andrew Olmsted's final post (given to a friend to post in the case of his death)

.................

And both of those are reminders of 5 little words worth keeping in mind: It can end so fast.
