During my work I am used to pair with my colleagues on basically anything. I do pair-programming when I develop software, we use pairing when we deliver trainings or when we write articles. I often do remote pair-programming with strangers. The most things I learned during the last years were by working in pair with someone I barely knew. Pairing for me has the following main advantages: I learn a lot from my pair. I extend my confort zone and I collaborate better with anyone. The product we work together is a lot better because four eyes are better than two. I will give examples from the activities of the well-known fictional character Sherlock Holmes on how his pair Dr. Watson helps him become better and finding the answer to their riddles.

“Data! Data! Data!” he cried impatiently.

obvious fact.”

10. Watson being a Navigator
“If I irritated him by a certain methodical
slowness in my mentality, that irritation
served only to make his own flame­like
intuitions and impressions flash up the
more vividly and swiftly”
