I can give my opinion about why some people are geniuses and others are not

There are a lot of people that we consider geniuses all over the world. They are mainly who they are because they have a special ability or talent, but also they master it until they become geniuses. What I mean is that you can have many talents, but if you don't try to do your best mastering this special ability, you will never be a genius in that area. In others words, you cannot become a savant if you are not able to practice and improve your skills. For instance, you could be a really good runner, but if you don't run frequently, you will not be the best athlete. It is clear that there are a lot of people that were born with one or more special talent, but most of them are not the very best with their abilities because they don't give the enough time or persistence to reach the highest level .
