No, it’s not about falling in love with someone at work. It is about taking a small subset of the work experience and overemphasising it’s importance.
For example say you work at a big company X. If we focus on just the fact that you are working at X, we will possibly not be able to fulfill our potential. This is because you could just be a tiny insignificant part of X, so being part of it might not even mean anything to them.
This is quite common with associating working overseas. It is nice to say you have got a job in a foreign country to everyone you know. Yet the job you are doing might be way less fulfilling than what you could be doing in your home country.
We must try not to oversimplify our position less be at risk of not delivering our greatest potential.
