Marc Andreessen is famous as a cofounder of Natscape in 1990's.
I discovered that he had his own weblog and had many good entries there.

One of my favorites is this post:

How to hire the best people you've ever worked
http://blog.pmarca.com/2007/06/how_to_hire_the.html

He is really good at summarizing things. He shows three most important criteria for startups to hire great people.

1. drive
2. curiosity
3. ethics

Hmm... I was most impressed with no1 "drive". He says that it is more important than being simply smart.

People with drive push and push and push and push and push until they succeed.

He's absolutely right. As a owner of a small business, I need more drive to get through the tough reality.
