The Rule Of 150 Says That Congregants Of A Rapidly Expanding Church, Or The Members Of A Social Club, Or Anyone In A Group Activity Banking On The Epidemic Spread Of Shared Ideals Needs To Be Particularly Cognizant Of The Perils Of The Bigness.

If We Think About Emotion This Way - As Outside-in, Not Inside Out - It Is Possible To Understand How Some People Can Have An Enormous Amount Of Influence Over Others. Some Of Us, After All, Are Very Good At Expressiing Emotions And Feelings, Which Means That We Are Far More Emotionally Contagious Than The Rest Of Us.

To Be Someone's Best Friend Requires A Minimum Investment Of Time. More Than That, Though, It Takes Emotional Energy. Caring About Someone Deeply Is Exhausting.
