Followup toThe Most Important Thing You Learned

What's the most frequently useful thing you've learned on OB - not the most memorable or most valuable, but the thing you use most often?  What influences your behavior, factors in more than one decision?  Please give a concrete example if you can.  This isn't limited to archetypally "mundane" activities: if your daily life involves difficult research or arguing with philosophers, go ahead and describe that too.
