Being a Teacher is not an easy task. If you are teacher by chance then it will not make any impact your student but if you are a teacher by choice it will make a huge impact.
Teacher is mostly responsible for the society as whatever he or she teaches to students they will learn. But as per current condition of education field we have lots of teachers just by chance not by choices that are ruining future of education.
Teacher by choice will use every possible way to explain particular topic to students and teacher by chance will not might because himself is unknown to the concept.
As a student you can easily identify your teacher whether he or she is teacher by choice or by chance. Simply if you understand whatever topic your teacher is trying to explain you then it means your teacher really works hard to make it done and it confirms that he or she is teacher by choice. It also confirms that teacher is in teaching profession not because of current job trends.
I am also a teacher and working in this great profession from last 9 years. I enjoy it. I love my students. I am taking engineering graphics subject for first year degree engineering students. I always feel proud as I am giving capable engineers to the society.
If you want to be a teacher or if you are a teacher then be like teacher by choice not by chance as it will destroy yours as well as your students career because you will not able to give what students always wants.
