ENFP - The "Advocate"

About the ENFP
"They can't bear to miss out on what is going on around them; they must experience, first hand, all the significant social events that affect our lives."

- The Portrait of the Champion Idealist (Keirsey)

"ENFPs are warm, enthusiastic people, typically very bright and full of potential. They live in the world of possibilities, and can become very passionate and excited about things. Their enthusiasm lends them the ability to inspire and motivate others, more so than we see in other types. They can talk their way in or out of anything. They love life, seeing it as a special gift, and strive to make the most out of it."

"Friends are what life is about to ENFPs, moreso even than the other NFs. They hold up their end of the relationship, sometimes being victimized by less caring individuals. ENFPs are energized by being around people. Some have real difficulty being alone, especially on a regular basis."
