Hi there, how is everyone there? Did you miss me again? HHmm! interesting thinking all of you, So here is the topic that we want to talk about. So shall we talk about the world's most hardest job in the world? Good, now we are talking. You see some jobs are good for basic in career, but let me tell you that these jobs are very difficult to do, but some times  these jobs can give a good experience in learning for life changing, although in these jobs it's hard to change life, but those who do this job, I tell you ask them, that how do they manage their jobs and how do they enjoy very well. So are you guys thinking about which job I am talking about? Let me discuss on it then, those jobs are few but reliable to for career in the basic, to make everyone confident, reliable on working, learning new skills, so now let me tell you their names, first one difficult but it's basically good for learning a confident and reliable, the first one is a call center job, yes this is the job where everyone sees themselves in a difficult job but they can have a good experience and good skills, now we move on the second job and that job is most difficult sometimes, more harder  but it's a good job too, like we can visit to the favorite places by visiting to other cities and countries,  like one place to other place, so this is why this job is good too and it's name airport job, like they serve foods, drinks, teas coffees and their care for their pessengers is a wonderful experience in their own job, so my request is please do respect for them and appreciate their jobs and their care, because without their services airport jobs are never too good to handle friendly and carefully.
