"Quote of the Month: Never Make a Bad Move Quickly
On the surface, the axiom, “Never Make a Bad Move Quickly” appears to be stating the obvious. What does anyone gain from knowing they should not make a bad move quickly? And what is the sense of warning them? Yet there is much wisdom to be gained by understanding this principle!
Moving too quickly is one of the most common causes of unnecessary mistakes. I see this error being made multiple times each day! Stronger players almost never make this mistake, yet weaker ones commonly do, so there must be some correlation between understanding and eliminating this error and becoming a strong player."
