<p>Unfortunately, Unabomber is not alone and nobody can prevent genius or just good / hard working on an outside person to be sicko inside, even the one who is raised in a family with other completely normal siblings.</p>
<p>The original question though was what separates genius from the merely accomplished. It seems that it is not that important and being genius will not quarantee success. There are savants with super human abilities and some of them are enourmosly successful, but they cannot even live independently, not being able to tie shoes and feed themselves. Would anybody like to be such a person? However, they are happy in their own world. These are truly geniuses with abilities that science cannot explain yet.</p>
