Give me six hours to chop down a tree and I will spend the first four sharpening the axe, said Abe Lincoln. Astonishing how much profoundly practical wisdom is packaged into that simple declaration. Time spent in sharpening the tool is time well-spent; so is time spent in thinking through a problem and thoroughly understanding the problem before rushing off to solve it.
