@AsianReaper - Refer to Sakumo Hatake background, "His son, Kakashi, proved himself a genius like Sakumo and idolised him, desiring to become just as great a ninja as his father." Bottom of same section, "Eventually, he committed suicide, which drove Kakashi to live strictly according to the Shinobi Rules."

It doesn't say specifically he had a mental block, however, his idolization of his father drove him to become a great ninja while young - but this was definitely negative emotion causing him to act such ways.

For the Sharingan, I didn't say the Sharingan gave him intelligence, however, I said that he acquired intelligence via the Sharingan. We know in the world of Dojutsu that once the user has the ability "unlocked" - to which, they have the ability to use their ocular jutsu, a whole new world of inspiration is opened up for their range of jutsu.

Many dojutsu users, notably Madara, Obito, Sasuke, Nagato, etc. were able to "access" jutsu easily and could easily try things that they believe they can do.

Inspiration would come from a variety of sources, but their time in training was significant and even accelerated - giving them apt to better learn jutsu quicker and improving their intelligence overall.
