In Scotland over many years we have cultivated through our justice system what I hope can be described as a 'culture of compassion.' On the other hand, there still exists in many parts of the U.S., if not nationally, an attitude towards the concept of justice which can only be described as a 'culture of vengeance.'
Culture is a sham if it is only a sort of Gothic front put on an iron building -- like Tower Bridge -- or a classical front put on a steel frame -- like the Daily Telegraph building in Fleet Street. Culture, if it is to be a real thing and a holy thing, must be the product of what we actually do for a living -- not something added, like sugar on a pill.
I have made decisions that turned out to be wrong, and went back and did it another way, and still took less time than many who procrastinated over the original decision. Your brain is capable of handling 140, 000 million bits of information in one second, and if you take hours or days or weeks to reach a vital decision, you are short-circuiting your most valuable property.
