I came back to Shanghai last Saturday. To be honest, after stayed in Midwest US for long time, I felt not very comfortable at Shanghai. The most obvious thing is the physical distance between people is much closer. The traffic and the (need to) walk instead of driving. I am not complaining here. I think similar thing will happen to me if I move to New York or LA.
On the other hand, getting out of my comfortable zone gives me new perspective about the “boringness” of life in Midwest. I guess a lot of times, we just can not get the best of the both the world. It all depends on what you treasure/appreciate most.
This applies to work place too. If we do the same thing for a long time, we are good at doing it and will feel very comfortable. Sometimes we are afraid to try new things. This way we may not grow much and achieve the full potential in our career.
