Never say 'no' to adventures. Always say 'yes', otherwise you'll lead a very dull life. Ian Fleming
I should like to save the Shire, if I could - though there have been times when I thought the inhabitants too stupid and dull for words, and have felt that an earthquake or an invasion of dragons might be good for them. J. R. R. Tolkien
It is just like man's vanity and impertinence to call an animal dumb because it is dumb to his dull perceptions. Mark Twain
Some men like a dull life - they like the routine of eating breakfast, going to work, coming home, petting the dog, watching TV, kissing the kids, and going to bed. Stay clear of it - it's often catching. Hedy Lamarr
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. Arthur Conan Doyle
