WOW! This part was impressive to me. I have always had a difficult time being able to put into words the way I think about things, how it differs from T's and how intuition and feeling combine. It may not be exact as INFP/ENFJ are quite different but you still did a great job. You made me want to attempt to explain it!On Fs:
When I (as an INFP) am given topic X to consider, my first question tends to be something along the line of "What else is similar to this topic?" So I cast a wide net in my memory and try to remember similar or related topics in order to provide context for topic X. The more context I can provide, the more meaning topic X seems to acquire and the more insight I gain into the workings of context X. Random associations are productive in that they provide new contexts; whimsicality is one means of encouraging and exploring new associations.
Associations are often intertwined with emotions, so emotions are welcomed and viewed as a productive means of pursuing associations. (That is, emotions are recognized and accepted by Fs as a tool for examining topic X the same way that logic is recognized and accepted by Ts as a tool for examining Topic X.)
