Grief comes and goes, it ebbs and flows. I think one of the lessons of this for me is that there's no one way to grieve. Everyone does it in their own way, in their own time, and we all process life and its challenges and its ups and downs as they come.

But the upside of painful knowledge is so much greater than the downside of blissful ignorance.

If you're offered a seat on a rocket ship, don't ask what seat! Just get on.

Facebook is a really exciting place trying to do something really important that I really believe in. And it matters.
