Education trains our brain and makes us smart

Education it’s very important in ourselves, we need to be well educated to live the life that everyone is hoping to get , but the question is do we go to school then college and university just to get the job that pays high wage or to get the dream job or just to be educated and can education make us smart or we born to be smart, some of my friends think that we inherit smartness maybe it’s right and maybe we feed our brains with education and then we get to be smart who knows. But what I discovered that reading feeds our brain it’s like training day by day it gets better then our thinking improves and by this we get to be smart, so my conclusion is education from school to college to university trains our brain then makes us smart. it’s just my opinion.
