Hey, size works against excellence.

When Paul Allen and I started Microsoft over 30 years ago, we had big dreams about software. We had dreams about the impact it could have.

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.

I think given all the different imperatives - getting energy to Africa, security of energy, climate change, that we should be spending half as much as we spend on health, which will get you all the way up to $15 billion - the health people don't like it when things get compared to their number.

If GM had kept up with technology like the computer industry has, we would all be driving $25 cars that got 1,000 MPG.

We flew down weekly to meet with IBM, but they thought the way to measure software was the amount of code we wrote, when really the better the software, the fewer lines of code.

Often you have to rely on intuition.
