"My mind rebels at stagnation. Give me problems, give me work, give me the most abstruse cryptogram, or the most intricate analysis, and I am in my own proper atmosphere. But I abhor the dull routine of existence. I crave for mental exaltation"

This quote by Arthur Conan Doyle speaks to the requirement for mental stimulation and difficulty. He expresses his disdain for the mundane and dull regimen of daily life, and rather craves for mental exaltation. He is drawn to tough problems and complex analyses, as they offer him with the psychological stimulation he needs. He is in his own component when provided with a challenge, as it enables him to use his mind to its maximum potential. This quote talks to the significance of difficult oneself and pressing one's borders in order to reach one's complete potential. It is a pointer to never ever go for stagnation, but to constantly strive for mental exaltation.
