What about academic subjects? What if a child does not want to learn academic subjects?

Everything is worth doing and learning, so there’s no need to divide learning by subjects or as academics and extra-curricular.
Also a lot of so-called academic learning (like language, science and maths etc) is already integrated in life, in doing stuff. For example, cooking involves reading, talking, mathematics and loads of science.
However, some families want to give importance to some ‘subjects’ and obviously if the child is okay, the child may include it in his/her plan.
Just realise that we can learn any academic concept at any age. Child can, if the child needs it, learn the concept of trigonometry at 30 years or understand chemical reactions if her job involves chemistry.
