I was impressed to see the tremendous impact @gestamp ’s apprenticeship program is having on students and their community:

Technology has made it faster and easier than ever before for people everywhere to give. I’m inspired by how many people from all over the world participate in #GivingTuesday .

I really enjoyed sitting down with @reidhoffman  to talk about the role great cofounders and partners have played in my career, like Paul Allen at Microsoft and @melindagates  at the Gates Foundation. You can listen to our conversation here:

I'm a big fan of @SiliconHBO  and was excited when they asked me to appear in the series finale tonight. #AlwaysBlue 

I’ve read a lot of great books this year. Here are some I think you’ll enjoy reading over the holidays.

Diane Tavenner had a simple but very ambitious goal: “We wanted to teach kids not just what they needed to get into college, but what they needed to live a good life.” You can read an excerpt from her wonderful new book on my blog.

Here are two amazing statistics: primary health care interventions could save 60 million lives in low-and middle-income countries and increase average life expectancy by 3.7 years by 2030: #HealthForAll 

I was deeply moved by Tayari Jones’s story of a married couple whose lives get torn apart by an incident of injustice. The book is so well-written that you’ll find yourself sucked into it despite the heavy subject matter.

This new treatment is a gamechanger for millions of people living with HIV in South Africa. I’m optimistic that it could help #EndAIDS  around the world.

Back in my early Microsoft days, I routinely pulled all-nighters when we had to deliver a piece of software. I even stayed up two nights in a row on occasion–I don’t recommend that. This book taught me a lot about the importance of a better night's sleep.
