Great companies start because the founders want to change the world... not make a fast buck. Call me a romantic, but I think entrepreneurs should try to change the world. This comes from working at Apple... old habits die hard.
I love the notification system on Google+. If someone mentions you, you get notified via Gmail. That's very useful for someone like me.
What I learned from my kids is that the greatest joy in life is not from material trappings, power, or visibility. The greatest joy comes from your kids. Nothing is even close to my kids in terms of bringing me joy.
I don't think Steve Jobs nauseated people when talking about how great Apple stuff was. The reason why he didn't nauseate people is because it was true. The start of all great marketing is to have a great product.
I've been all over the world meeting with companies and startups and entrepreneurs. And I tell you, they are more similar than different.
Smart, well-meaning people get it wrong when they start believing that the world owes them something and that the rules are different for them.
