Talk to more INTJs. Stalk them like your gym teacher does in the locker room. You are an ISTJ, so we're your best chance.
Don't take things as they were or are. A thing doesn't have to be what it seems or what it used to be.
When you see an object, imagine what that object might be used for but never has been. Think with ingenuity.
Think in terms of possibilities, not actualities.
When you listen to someone speak, read between the lines. Try to guess what the person really means, what they're thinking and feeling beneath the words. Interpret them. Interpret everything.
Get a feel for the deeper meaning behind appearances. Try to imagine what lies, or could lie, just on the other side of how things seem.
Pay attention to the idle images that flash through your head. Find an image--the more abstract, the better--and take hold of it before it vanishes. Try to understand what the image is telling you, what it means. Take a similar approach with dreams.
Consider how people typically view a problem or situation, and then try to look at that problem or situation in a way that neither they nor you have ever thought of. If your new perspective doesn't come packed with the solution or an insightful interpretation, keep shifting your perspective. As you shift your perspective, try to listen for that inner feeling that guides you toward insight, and obey it.
Imagine that you are focusing on a lamp near you. With little effort, you can see its shape, color, design, and can use that data to determine if you like, dislike or feel neutral toward it. Now, focus inside and let your mind produce associations that the lamp evokes. Relax, and let your mind explore and play with the image of the lamp. If you find it easy to unfocus your attention from the external lamp and follow the associations and impressions it evokes, you probably have learned how to switch from sensory attending to intuitive processing. If you try to focus internally and your mind is blocked with the physical reality of the lamp, then you are having difficulty accessing your intuitive processing on demand.
1. Learn to get quiet and focus internally.
2. Practice deep breathing as a method of slowing down, relaxing and looking internally.
3. Select an external sensor object, close your eyes and let your intuitive mind play with the object. Don't control or judge -- let the intuitive mind expand, flow and invest ways of looking at the object.
4. Observe several people in a room. Consciously see the pattern in which they are standing. See the objects in the room as colors only, or in hues ranging from light to dark, or in terms of tall or short.
5. Unfocus attention to the details of a situation and see what it reminds you of. Let the mind produce some associations, some patterns.
6. Sensors tend to see what people are doing now. Use an exercise in which you imagine them in the same room five years from now. At first sensors may feel silly stretching the mind in such a way. Remember: the sensing perception is an actuality process and the intuitive perception is a more flexible possibility process.
From a book I have:
All of this stuff is good. There's actually a lot more information about it in the book, another 1-2 pages. The one thing that bothers me is the book telling you to look for associations or seeing what something reminds you of. How do you differentiate between an intuitive leap and introverted sensing kicking in if you're an SJ?
Beat, you don't want INTJs and their crappy Ni. Turn to an INTP, and you'll get the greatness of Ne filtered to perfection with Ti.
