After working as an English teacher in a primary school for about fourteen years, I am thinking of taking the CELTA in order to upgrade my career and get a better job opportunity. In addition, teaching for a long time in the same way has left me bored. So, I need to refresh my way of teaching and add something new to my work. [You did a nice job. A few minor changes were all I made. Good luck with your career change efforts. Hope you found my comments helpful.]
