"I’ll share my “aha” about the power of the snapshot (Snap Shots of Type)as a type deep-dive. When I was coming back from the last Beebe conference, as we were taking off, the airline attendant gave her “…in case the air masks fall, cover your own face and then the person you are traveling with” spiel. A thought went through my head, “What if I cover my own face and turn to the one that I’m with and say, ‘Good luck to you!’?” I laughed and then thought, “Why do I always do that?” (have that silly kind of humor.) Minutes later, I started reading through the INFJ type snapshot and read the Te as trickster: Approaches logic with silliness and I was just blown away because I had just done that with the mask thing. It was amazing to me that I was not the only one who did that and that there was a pattern. That really validated the power of this deep dive for me. Thanks a lot. (You can find Snap Shots of Type on our website under "Books and Materials".)"
