Natural speed, please. Try to pronounce properly and avoid noise in the background.
Most of my friends went into teaching actually. I think they felt it was more 'academic' and of course the pay is quite a bit better. But I've never really been bothered about things like that. I think the enjoyment of the job comes first and I certainly get a lot of good feelings doing this work.
We have some difficult cases sometimes but there's still a lot of laughter here and the patients can be amazing, especially the kids.
I'd recommend it to anyone who likes helping people.
Thanks!
