In my view, it's irreverence, foolish confidence and naivety combined with persistence, open mindedness and a continual ability to learn that created Facebook, Google, Yahoo, eBay, Microsoft, Apple, Juniper, AOL, Sun Microsystems and others.

Microsoft has complied with our request, as has Yahoo and AOL. We have not analyzed the data yet.

Imagine the world of mobile based on Nokia and Motorola if Apple had not been restarted by a missionary entrepreneur named Steve Jobs who cared more for his vision than being tactical and financial.

Certain food-based biofuels like biodiesel have always been a bad idea. Others like corn ethanol have served a useful purpose and essentially are obsoleting themselves.

Seeking an acquisition from the start is more than just bad advice for an entrepreneur. For the entrepreneur it leads to short term tactical decisions rather than company-building decisions and in my view often reduces the probability of success.

Will biofuel usage require land? Absolutely, but we think the ability to use winter cover crops, degraded land, as well as using sources such as organic waste, sewage, and forest waste means that actual land usage will be limited. Just these sources can replace most of our imported oil by 2030 without touching new land.
