Ask an Engineer to draw a straight line through 3 arbitrary points on plane, and the Engineer asks, how thick can the line be? People always says this like it is a joke on Engineers, but I really think these Engineers are smart!
Then there is the story of The Hare and the Tortoise. The Hare, confident of winning the race against the Tortoise, stops to look around, smell roses, eat carrots, take a nap, and ultimately loses the race to the slow but steady Tortoise. When I hear this story, I think, if I were the slow and steady Tortoise, I too will still stop, smell roses, eat and nap, along the way.
A colleague, in natural flow of conversation, told me, (s)he was thinking of problems with the``career graph''. There are so many graphs, social, societal, vehicular, .. whatever, why not the career graph.
