Wisdom in class - and other contexts

One of the greatest examples of true wisdom is knowing when and when not to speak.  That is particularly apropos in a classroom or small group setting.  Particularly challenging for a teacher or leader is the person with a good deal of knowledge who always feels the need to say something - whether its relevant or helpful or not.  Many of us who are natural talkers have room to grow in this area.  That may include you.  Obeying the following chart can help immeasurably.  Hopefully you'll find it as helpful as I have.
