Hi Bill and thanks for doing this. I recently read 2017 annual letter in response to Warren Buffet on the impact of his donation (2006) to your foundation, and the world it serves, and I thought the information you highlighted was incredibly powerful and insightful. For those of us that cannot start our own foundation, or even if we could, how do you recommend finding a cause worth fighting for? Clearly your access to information and resources has allowed you to isolate some of the world's larger problems and find those folks who can actually make a difference. But where did you start? (For those who haven't seen it- https://www.gatesnotes.com/2017-Annual-Letter?WT.mc_id=02_14_2017_02_AL2017GFO_GF-GFO_&WT.tsrc=GFGFO)

Lastly, can I ask for your opinion on the status of the world refugee crisis. I've seen a lot of information on both sides of the fence, but I think I lean towards the belief that charity/donations need go into these communities and the folks that relocate are often the top thinkers/earners that could truly change their home country if they stayed. Here is a rather oversimplified video that summarizes the basis of my thoughts, I'd love to hear your view on all of this. (Poverty/refugee by numbers- https://youtu.be/LPjzfGChGlE)
Thanks again for taking the time. You truly are a visionary, role model, and hero without a cape to many of us worldwide.
