Entrepreneurs don't write a 100-page business plan and execute it one time; they're always experimenting and adapting based on what they learn.
Golf has an ambivalent relationship with the environment. On one hand, it's a great preserver of open spaces. Golf doesn't pave the world - it helps to green the world. But the downside is, it uses a lot of fertilizer, pesticides and water.
You take one bomber and deploy him in Baghdad, and another is manufactured in Riyadh the next day. It's exactly like when you take the toy off the shelf at Wal-Mart and another is made in Shen Zhen the next day.
We are led by lawyers who do not understand either technology or balance sheets.
No matter where I go - London, Beirut, Jerusalem, Washington, Beijing, or Bangalore - I'm always looking to rediscover that land of ten thousand lakes where politics actually worked to make people's lives better, not pull them apart.
We've gone from thinking the fuels that powered our growth were inexpensive, inexhaustible and benign to understanding they are exhaustible, expensive and toxic. Once you frame the problem that way, people will look at solutions differently.

Supply chains cannot tolerate even 24 hours of disruption. So if you lose your place in the supply chain because of wild behavior you could lose a lot. It would be like pouring cement down one of your oil wells.
When I was growing up, my parents told me, 'Finish your dinner. People in China and India are starving.' I tell my daughters, 'Finish your homework. People in India and China are starving for your job.'
Basically all the world's computer parts come from the same supply chain that runs from Korea, down through coastal China, over to Taiwan, and down to Malaysia.
Many jobs at Google require math, computing, and coding skills, so if your good grades truly reflect skills in those areas that you can apply, it would be an advantage. But Google has its eyes on much more.
I can see a day soon where you'll create your own college degree by taking the best online courses from the best professors from around the world - some computing from Stanford, some entrepreneurship from Wharton, some ethics from Brandeis, some literature from Edinburgh - paying only the nominal fee for the certificates of completion.
