Why good parenting is easy and impossible at the same time

We all know how to be good parents. Be loving; show affection. Be firm and consistent. Give praise for good behaviour or learning new skills. Don't lose your temper. Set clear boundaries. Be a good example. When toddler behaves badly, stay calm and tell him why you are unhappy; neither give him what he wants nor get mad.

It's so EASY. It's so bleeding obvious.

And yet.

You have be superhuman to actually do it every day.
