I wonder if this happens to other ENTP's. I don't just loooovve learning ANYTHING at ANY TIME like some NT's do. I need a trigger. Maybe I'll be conversing with someone and they'll present me with some totally new and fascinating idea, and suddenly I'm FULL of energy, I just start voraciously ingesting as much as I can on the subject. Talking to others, researching online, planning what I'll do with it. This will go on for hours (I'll look at the clock and be shocked that it's already 3:30am), and eventually the day ends, I have to sleep. So I go to sleep thinking about all the new things I'm going to try tomorrow, and how this thing has totally changed my life, and omg it's so awesome ... And then the next day I wake up, look around in disbelief at the aftermath of my learning session (notes, stuff I got out) and I'm like "oh ... yeah, right .. I was meaning to work on that thing ... god, I'm hungry, well, maybe later on. Wow, my head hurts ..." And that initial spark of inspiration is just gone. And I just want to do something completely mindless. I see it sort of as mental overload, and the next day my thinking muscles are sore and they just need to rest.
