The secret of raising an academic child is to have a child who enjoys concentrating on and chooses to concentrate on academic subjects.... What a surprise. Sarcastic
.
If your child chooses to concentrate on wood carving, they will become very good at that, but won't be considered academic. If they concentrate on playing several musical instruments, they probably will become very good at that (but won't be considered academic, funnily enough they will be considered musical instead)...
Maybe you could trick your child into becoming academic, by developing their powers of concentration playing games they enjoy and focusing on whatever they find most interesting, then when they reach a certain age, tell them that they will now use their powers of concentration to study maths and English, instead, whether they like it or not.
