Career Path

I have always been thinking of a good definition for the word"Career" , when I graduated from my under-graduate school I did not think for a moment that I am going to work only in my field of study ! . I felt confident that I would be able to work wherever I find myself able to get the job done as it should be.
My first job started at a big company in Jordan which is Americana company for restaurants and tourism projects , My job was to study the places where they will open new restaurants,collect information about the area,analyze the customers preferences and desires, and then make a recommendations . I did my job and I almost was spending half of my day roaming those areas and meeting with people ,and my recommendations hit the target and exceeded the desired outcomes from my bosses.
My second job was very important, I was interviewed by the International Airport top level officials to be a supervisor of the VIP passengers services. I got the job after three interviews and started working and dealing with high level passengers from all over the world . I stayed in that job for one year and a half .
My third job was the one I loved which is teaching , I read an announcement for a job in UAE ,they were looking for a supervisor and business teacher , I applied , I was interviewed twice one in person and one on phone and I was given a test and finally got the contract .I went there and I taught for two academic year and I loved it .
Therefore, I find it interesting when talking about career , that does not mean I have to stick with my field of study but always when I think of my career or what I am looking for ,I will ask two questions and then match the answers if they match I will go ahead and take it if not then I am not gonna take it : what is my strength I mean what is my core of competence ? what does the job need done?
