Here the young person will recycle through all the previous stages again, only this time they go at twice the speed. So there will be a new period of 'being' aged 13, when they will spend time resting, eating and thinking about sex. This is followed by a further period of 'doing' where our young person has the opportunity to re-explore the world with a better understanding of her environment. At about 14 our developing adult revisits the stage of 'thinking'. Here previous decisions are reviewed and revised. So in the ensuing stage of 'identity' the early decision about who we will be are updated in order to fit in with the grownup world we now know better. This is followed by a further period of 'skill' development. In a way making sense of and structuring the world as we experience it, so as to prepare for our 'friendly divorce' from our carers.
