Rules that made Google successful?

I was researching about senior and accomplished computers scientists and came across a very good section on wikipedia. In this section Google’s earlier success was down to the following rules:

Don’t delegate: Do everything you can yourself to make things go faster.
Don’t get in the way if you’re not adding value: Let the people actually doing the work talk to each other while you go do something else.
Don’t be a bureaucrat
Ideas are more important than age: Just because someone is junior doesn’t mean they don’t deserve respect and cooperation.
The worst thing you can do is stop someone from doing something by saying, “No. Period.” If you say no, you have to help them find a better way to get it done.
