IME most ENTP children are found either outside exploring (and often inadvertently wandering miles from home—without fear of getting lost) or inside reading lots of factual books. If you were an ENTP child, you were probably fascinated by dinosaurs (male/female) and you probably spent a lot of time memorizing tons of facts about them (and other animals). You probably memorized their scientific names and how they fit into their habitat/ecosystem. It may have been more difficult for your parents to get you to read stories about people or fantasy until you hit about 5th grade. You may also have found yourself getting in trouble for taking things apart to figure out how they work for trying to fix (Jerryrig) things around the house.
When you hit your teen/young adult years, your Ti began to try to make some kind of sense out of the many random and seemingly contrary ideas that were fighting for supremacy in your head. So you began to talk to people about their ideas. Without wanting to seem like you didn’t know something, you may have even pretended to know a lot about someone’s specialty by asking a question about it based on one of the facts you randomly found about the subject. Trusting them to dominate the conversation you absorbed all the information they gave you, carefully analyzing and classifying and integrating it into your world view. You may have found yourself playing the devil’s advocate just to find out what ideas people truly believe and why and then suddenly switching sides mid argument. (Part of this is because your Ne sees the validity in multiple sides of an issue and you want to be clear on your own beliefs about said idea). You may have been annoyingly precise about other people’s ideas always trying to clarify and define the terms as you went along without considering their feelings. You probably also recognized immediately when someone (like a teacher or parent) didn’t know what they were talking about and immediately dismissed them. You also probably began enjoying the humor of things that are absurd or paradoxical (such as Monty Python or Mel Brooks comedies). You also probably started exploring the validity of non-conformist ideas (such as researching the ideas of the English/French anarchists of the 1800s) or started engaging in risky/extreme behavior (such as breaking into a castle after midnight or swimming out to drink a beer on someone else’s boat.)
By 25, you probably began to feel embarrassed that your arguing sometimes gave you the appearance of being a “jerk” or of not being some one whose words/ideas can be trusted. Maybe someone you respected said you were not being precise enough (exaggerating a concept) or was tired of your “excuses” for unfinished projects or bailing on them when something more interesting came up. You started worrying that you were earning a reputation for being inconsistent and undependable. Finally you started to recognize the need to settle down and find someone to share your ideas/and life experiences with. In dating however, you have grown tired of "trying people on for size until you get bored of them." So you find your technique to be a bit more business like and to the point because you don’t want to waste your time dating for dating’s sake. You may even offend people on the first date with your to the point questions about their beliefs or statements about your own. But you don't care because you want to find a partner who understands your unique way of looking at the world and excites you with their own perspectives.
As you mature, your last preference (Si) probably gives you an amazing memory in which you can analyze the present moment and compare it to the things you experienced in the past. You may even find yourself remembering things from your friend’s past that they, themselves forgot. You may also find yourself becoming a student of history in order to understand the present and project the future, and while becoming a lot more respectful of conservative ideas than you were in the past.
Finally, you are the sort of person that needs to understand the whole in order to remember the facts about it. Perhaps you had a breakthrough in high school or college when you realized that the more you understood an object’s/person’s place in history the more you would understand it’s scientific/mathematical/religious significance. Or in simpler terms you needed to understand the workings of the entire company and your specific place within it in order to remember the details of your job.
Again, this is in my opinion from studying the ENTPs I have met.
I would say that from what I know of you, Ti definitely outweighs Te because you are concerned with definitions, categories and reliable data before committing to a perspective.
As for the other functions . . . time will tell. : )
