Why should I care that Apple achieves a certain revenue, or equally that they are doomed because some person on Twitter says so. I am focused on what a difference the products make to my life, what they do for others, and what I can do to help people get the most from their device. I am not bothered how many iPhones sell in China (or anywhere) all I care about is if I buy one or not.
I think this is a good attitude. I want to develop the same attitude.
