"Most consequential choices involve shades of gray, and some fog is often useful in getting things done"

This quote by Timothy Geithner suggests that when making crucial choices, it is often difficult to determine the right course of action. Rather of trying to find a well-defined option, it is often much better to accept that there are numerous viewpoints which the best choice might be a compromise between them. Moreover, Geithner suggests that it is sometimes useful to have a particular level of ambiguity when making decisions, as it can help to move the process forward. This quote encourages us to be open-minded and to acknowledge that there is rarely a single, appropriate response when making essential choices.
