The N/S conflict manifest in another way imho. In me it is the push-pull between wanting to spend my time learning, reading, thinking, and zoning out and the need to do things that benefit only my physical upkeep like going shopping to purchase new clothing, which I really dislike doing, getting groceries, getting my car repaired, cooking which I consider it a waste of time, and stuff like that. My ISFJ and ESFJ mother and grandmother seem to live to do these kinds of things and really enjoy them, while I feel that doing these things often distracts me from more interesting thing like thinking about stuff. I also feel that if I do things without spending a lot of time thinking beforehand, that I will make wrong choice and as a result spend a lot of energy in the wrong direction. From this comes indecisiveness.
The MBTI test is a very crude measure of how much of each cognitive function you use. And it can be influenced by whatever state of mind you were in when you took the test. I think observing yourself from aside and seeing what you like to do most of your time is a much better measure of it. For example, I excelled in school in subjects that required me to operate with concepts and hated those that had me memorizing detail. I am not very attentive to people's appearances and have dated short ugly nerdy guys who were really intellectually stimulating to me (my sensor mother always complained about them primarily telling me that I should pick taller cuter looking guys). So it was clear to me that I am very strong in intuitive cognitive function and quite weak on the sensor part. On MBTI test I tested only 10 or 20% N however, which was wrong.
In the end I think it is best to have a balance. While I enjoy my N, if given complete freedom it will make me incredibly lazy in certain areas of my life. Sometimes for example I forget to eat when I am learning about something very interesting, which is not good for my health.
I think what you are trying to do is perhaps extravert your intuition rather than suppress it in favor of S. ENxPs for example go around life doing a lot of stuff, even though they also have intuition as primary function. This is because their extraverted intuition shows them many different opportunities and instills optimism into them. We can sit around and think for a long long time about stuff while they just jump up and and do something. Albeit they also lose out because they don't think things through as thoroughly as we do. So if you want to behave more like them, instead of focusing on what you already know and examining and reexamining the evidence, think about the future, what can you do with what you know, focus on creating future possibilities. You'll have to just force yourself to pick best decision you have made up to date, suppress your worries about making wrong choice, and then move on to something new. Just like ENxPs do it. Our basic instinctive drive is to sit there and contemplate for as long as we can, but life isn't infinite and sometimes we just have to settle for "good enough" decision and forcibly push ourselves in one direction or another.
