Introversion (I)

I like getting my energy from dealing with the ideas, pictures, memories, and reactions that are inside my head, in my inner world. I often prefer doing things alone or with one or two people I feel comfortable with. I take time to reflect so that I have a clear idea of what I'll be doing when I decide to act. Ideas are almost solid things for me. Sometimes I like the idea of something better than the real thing.

The following statements generally apply to me:

• I am seen as "reflective" or "reserved."
• I feel comfortable being alone and like things I can do on my own.
• I prefer to know just a few people well.
• I sometimes spend too much time reflecting and don't move into action quickly enough.
• I sometimes forget to check with the outside world to see if my ideas really fit the experience.
