Lest my post about Type 1's come across as too negative, let me add that all 9 types have positive and negative qualities. I just quoted the Average zone, because Level 5 mentioned being afraid of making mistakes.
Without Type 1's we would not be sitting here in air-conditioned (or heated buildings) with cars in our driveways (or garages) writing on computers. Type 1's are the people who make sure the trains run on time, that when you flip a switch in your home the lights come on, that the books in the library are filed correctly even if no one is there to see them.
Who would you rather have in charge of your local nuclear reactor-- fearless with her uncompromising standards of perfection, or Mr. Mojo (or me) who might just be too mopey and sad one morning to check out the flashing red light on that panel?
Perfectionism and standards are absolutely necessary-- and very appropriate for an engineer-- UNTIL you try to apply them to your own emotions/feelings. The direction of growth for the 1 is-- ta-DA!-- 4, which means more introspection, perhaps some artistic expression, acquaintance with and acceptance of one's own dark side.
