Interesting post from Rick Segal.
A good friend of mine works at Google. On my last visit to the campus, he said some interesting words which have stuck with me.
"How do I like the job? I'm scared shitless cuz we are a one click and they are gone kinda company with other apps that have to really compete."
I don't agree you have to be paranoid. I do believe you have to be acutely aware of what is happening in the market but also be prepared to listen to feedback from your customers and innovative ideas from the shop floor. Ideas plus excellent execution. We are all in a game without rules today and we have to make it up as we go along.
You can choose to see that as a constant threat or you can see change as a positive way to move forward. Yes its scary sometimes but you won't just learn about your business - you will learn much more about yourself.
