Some people I know decided not to try leaving their comfort zone. Most of them concern about the uncomfortable things that would happen, even before they actually came and see by their selves. Those things usually about the taste of local food that may differ, the daily cost that could be more expensive, how we pray at new place, etc. The last thing that really become my consideration is about "leaving our friendly neighborhood" and "losing our social network".
At first glance, I was same with them. Until I made up my mind to chase my carrier by compromising my comfortable. Then I left my comfort zone.
The truth about leaving comfort zone is “Sometime what we think is hard, could be much easier when we actually do it”.
