Long-term Vision And Product Strategy.

I Understand How Every Healthy Child, Every New Road, Puts A Country On A Better Path, But Instability And War Will Arise From Time To Time, And I'm Not An Expert On How You Get Out Of Those Things.

We Have Two Other Countries, Pakistan And Afghanistan - Again It's The Instability That Is A Problem There. So Over The Next Several Years, We Expect To Drive The Number Of [polio] Cases Back Down To Zero Because That Is Likely To Be The Second Disease After Smallpox That We Completely Eradicate.

Learn From Your Unhappy Customers.

Whenever You Have A Few Setbacks, The Idea That Half As Many Children Are Dying Now As Back In 1990 And So... It Was Over 12 Million A Year, Now It's Less Than 6 Million A Year. We Have A Clear Path To Get That Under 3 Million A Year And We Know What To Do. And This Generation Of Young Africans Is A Very Large Group.

People Are Building The Software And So Having The Pieces Be Such That A Single Person Understands All The Tradeoffs And Everything That's Going On In A Piece Is Extremely Valuable. It Avoids Getting Into An Experimental Mode Where You're Just Trying Things Out. That Never Works.
