Down voting me, Kinda harsh? I am not saying PG is the only reason people people are pursuing a startup, but I would argue he is responsible for giving some people the fortitude to go through with it.
For example, before reading PG's essays, even as a child I knew I wanted to be an inventor. Later in 6th grade my dad joined a start up as computer engineer (around 1997) and I was able to go to work with him on many occasions. This combined with the invention of the World Wide Web and home computers, resulted in me knowing I wanted to start a company that made internet applications. However, if it wasn't for Paul's writings I don't know if I would have had the fortitude to follow it through to the the point where I am now. I think a lot of other people can identify with this.
