This lesson covers my favourite skill and the one I use each and every day without any risk of over doing it.
In any situation you will always have one 'part' that you prefer to another. Therefore by using this skill you will never be lying, or be inauthentic. And you don't even have to know what you are praising.
Describing your favourite part is the skill most used by parents as there is no risk of overpraising or 'fake' praising.
