My mind rebels at stagnation. Give me problems, give me the most abstruse cryptogram, or the most intricate analysis, and I am in my own atmosphere. I abhor the dull routine of existence. I crave for mental exaltation. That is why I have chosen my own path, for I am the only one in the world.
This has been one of my favorite quotes (slightly modified by me). And it's from Arthur Conan Doyle.
