11am my think(jason)

I consider this matter...


I think that sturdy hard is most important thing

because If someone sturdy hard, his brain is developed well than others
but I think that sturdy hard is not only way to become smart
genetic factor, right handed, left handed is important,too
for example, there are 2group
first group is high IQ and brain size is bigger than the second group
If  2 group sturdy hard same effort, first group is smarter than second group.
But  this is happened  the same assumption but left handed people sturdy hard than right handed people about math
left handed people's brain can develop than right handed people about math 
my opion is that effort is important than genetic factor
and another example
it is true right handed people are easty to sturdy math  than left handed people
