There was a good quote from Greg Davies in yesterday's Metro -in answer to this question "Its a wonderful job if you want to be a teacher. You have to feel the calling. If you do, it's the best job in the world, but if you are hoping to do something else, it's not for you. I went into teaching wanting to be a comedian. I thought I'd teach for a year and I blinked and 13 years had gone by." He has also commented in the past how much he had developed his communication skills through teaching and how much he enjoyed being with the kids in the classroom. Increasingly people need to come into the profession with a clear perspective about the job and the workload. Teaching can be never ending unless you make it so! There is always preparation and marking to do but more importantly is the need to balance your work and personal life. Without that- then you burn out.
