I relate more to wing than tri-type, but I can't figure out the tri-type for the life of me. Sure I can take a test and get a result.. but it almost seems like it dilutes the meaning. I kind of compare it to astrology in the sense that you have all these planetary positions, sun, moon, mars, libra, venus, pluto, squares, trines, etc. Whenever you get into a highly complex system based on subjective interpretations, tremendous potential for misunderstanding.
Anyhow, I think I will find the basic core/wing fixations, growth and disintegration points to be enough material alone to keep me reeling on self actualization for some time. I don't discount that tri-types could be accurate or have value.. but for now I'm good, lol. =)
