8th function

I mean, i could use Te, and i use it on a daily basis to organize my work logically. Sometimes i even organize things for fun on a piece of paper with a graph of some sort. Is the devilish function really that devilish, though? It doesnt seem to give anyone too much trouble, from my experience...

What role does your 8th function play in your life, you know, that inferior subconscious one? For me, that's Ti. I feel like I can use ration and logic along with the best of them as regards other people, but when it comes to myself, it's like I end up just picking myself and situations apart...
