Good timing.. Just thinking about introducing Mercury (which has to do with learning but somewhat only understanding) and you posted this within a minute of those thoughts!
Cheers.
Well, I don't know if this is true for everyone - I have only seen it with S types in this way (although that's what, 75% of the population) though there was something about taking things whole and undigested from society without applying them personally. It's worthy of its own thread to discuss.
Well most of mine are from elsewhere - I just use them for the effect or because they sound good. It did inspire the writing of the Mercury chapter, not that it's likely to happen as I have to deal with SQL instead today..
Cheers.
