I am a teacher by profession. In my experience it's a difficult job disciplining students and talking loud to your students even if they don't listen
I am a teacher and I know what it is being a teacher. It is a tough job in the sense that the job keeos you awfully busy to the point of being unsocial. A teacher gets hardly any time to socialize. I can rather say that the job is very demanding. In other words a teacher has to keep herself updated according to the course she teaches and also the students way of acceptance and comprehension.
A teacher often has to adapt new methods to be candid in her explanation.I we view teaching in this perpective, teaching is a tough job, but for me it's an intesting and job satisfying job.
