This question is for the people that are still working. While I was there before and I learnt too.
When I was still working, I was teacher and I learnt care and patience. You need such attributes while dealing with kids. Any mistake you make, they are already crying and wailing so I cultivated the habit of being soft spoken and patient with them. It was fun all the same.
Days ago I was watching a documentary material about what you mention, and the importance that turns out to have at an early age, thanks to the fact that our brain is programmed to learn from the moment we are born, and after three years we tend to forget what is not important and what that we stop practicing!
Could you explicate further?
