How to develop NT?....
Find a way to connect a pig to a jellyfish. Think real hard about it even if it means being oblivious to the rest of the world, ie you missed your sisters wedding. This is important.
Once you have made the connection proudly proclaim, to anyone who will listen, that pigs and jelly fish are one in the same. When people start to give you weird looks, run off to be alone for a while so you can find a way to understand pigs, jellyfish, and weird looks.
Then forget everything you ever knew about fasion because...seriously? And become obstinate.
BAM! Instant NT.
