　　I got into the teaching profession by choice．I was then in 9th grade，when my mathematics teacher asked me to take a class for a few students to whom the subject seemed difficult．And believe me，I enjoyed the teaching．I never knew teaching would be so interesting．I loved my freshmen and was delighted to teach my so-called students who came up with lots of good questions．

　　After my post graduation，I worked as a software developer with a public sector（部门） in Bangalore for a few years．But I realized that no job could provide me the satisfaction that I experienced while teaching and training．In fact，I feel it was a timely realization for me to choose the teaching profession．I applied to a few colleges，and finally I was chosen as a"Lecturer"，and I had to lecture graduate and post-graduate students in a college．

　　On the first day，I was nervous thinking that I had to teach the senior classes．But now I can say that taking lectures was one of the best experiences of my life．I was a Computer Science and Information Technology Lecturer，but I tried to help my students with subjects that were not within my domain（范围）．It was a new feeling to me every morning before going to the classes．I used to feel energized and excited thinking that the class would be lit up with bright faces to greet me，"Good morning，Madam"．

　　To me each day was a new beginning，with new feelings，new experiences and new queries（疑问）．I loved to explore their young minds，read their inquisitive faces when a particular topic seemed tough．It was very challenging to motivate them to take part in the classroom，think critically，question and also respect others'point of view．Though few things never seemed easy，it was very exciting to assure them that they really can．That is the reason，I love to teach．
