I don't know - if I'm in a Ti session and I get really motivated about something, I sometimes want to call someone who I respect and bounce it off them - or I'll just have the rare urge to go hang out with friends so that I can laugh it up or get some pent up energy out of me. That's my Ne bursting out. It wants to "get out" - it wants to engage with other people. But, Ti overshadows it 85% of the time - for me anyways.
But, I think Ne comes into play when I'm alone. When I'm writing or devising a business plan or planning something out, I think my creative, "outside the box" ideas come partly from Ne. Like someone close to me recently had this really funny idea for a business. I went home and my mind just ran with it. I had this vision of how the whole business could work from start-up all the way to bringing the product to market (and everything in between). That's my Ti thinking, but I think Ti alone might make the idea kind of "dry" - just "another run-of-the-mill business" so to speak. With Ne mixed in there and knowing what consumers like and how the shelves at Toys 'R Us look - I'm able to be WAY more creative with the idea to the point that I believe it becomes a very innovative, cutting edge business idea.
The problem is, I have to turn around and use Ne (day-in and day-out for the life of the business) for it to become a reality. I only "want" to use Ne in short spurts - here and there. I don't necessarily want to deal with people and the outside world from 8-5 every day. So, until I engage Ne, it remains a "great idea" that is stuck in my head.
But, yeah, I think Ne takes my ideas to a new level. It takes them from mere "good ideas" to "creative, unique, innovative ideas" that *could* actually work in the real world - if I use my Ne!
