It might be worth considering what answers you give now that might be different than ones you gave 7 years ago. I know I took one of these back in college, and probably every 5 years or so I've revisited it, each time never recalling my previous result (what does THAT say about my personality?). 

But it struck me this time that some answers I gave this time would have been different 5 years ago. Enough that I probably would have been rated a different alphabet. 

For the record: ENFP   (slight, distinct, moderate, slight).

Like the sun over course of the day, our luminousity and spectrum change over time, from the blue tints of dawn to the harsh light of day, and again the blues towards dusk if I recall correctly, followed by gruesome darkness. 

Anyway forgive my lyricism, but you catch my drift (although some claim that people never 'fundamentally' change, I disagree).

I wonder if there's a way to measure how an individual is trending over the years, probably by comparing a series of tests over the years (although I think the act of taking thr tests repeatedly would tend to increase introspection, in the manner of observation effecting the outcome).
