i was expecting the hound to look like this

Hello people
im a complete opposite of Sherlock, but only in the bad ways
extremely unobservant, unintellectual, bad calculator, no awareness about anything that happens around me, a complete idiot that anyone can take advantage of, zero talent and no power
the ways im similar to him are only that i am bad at socialising, have no friends and i dont like or understand the humanity
all caused due to a lot of maladaptive daydreamin, addiction to sources of entertainment and other symptoms that grew over the two
i was introduced to Sherlock holmes by the movies. until then i only knew that he was a detective but not that he had an amazing brain that worked in amazing ways
then i read the books, and then then this great show
i really love how controlled, ordered, strong, and brilliant mind Sherlock has and how he can think in completely different ways and learn to function in better processes
i really hope that some day by some miracle i will be left fixed and with more chance to become like him. this hope being most of the reason i want to continue living
i will be looking at the forums frequently
 

i know that sherlock's deduction skills were inspired from a real person but i cant find out any person that had powers like him
so i was thinking wheather it is possible for a real human to have observation and deduction ability, totally controlled brain and powerful memory like sherlock? or is it just too unrealistic?
