    I just listened to this episode, and I am so glad that I found it. I 100% resonated with the expression of Ti as a holistic energy. I have been feeling very “stuck” in my job, and life in general really. I have gotten back into a “phase” of MBTI studies, where this time I am learning for the sake of developing myself rather than previous times where I wanted to simply understand myself more. The part about having a multitude of different mental models and expertise in none of them really hit home with me. I had become so open ended with my interests throughout early adulthood that I never truly got to the point of any of them. In a way I was analyzing and reasearching without an intentional goal or output. I wanted to think about interesting things because…why not, there’s so much to learn. With the two expressions of Ti I can see that analytic is much more about the quality of a few models and holistic is about the quantity of frameworks. I have now built up so many mental models, that I just go through life in a detatched fog while using my Ne to try and find a new model that clears that fog so I can return back to being my authentic self.
    Anyways, great episode! I have listened to a few now, specifically about INTP and ISFP (my wife) preferences. MBTI has the type of intrigue for me that makes me think I would enjoy mastery and expertise in it. I just have to find a way to combine that with my creative passion for video/photography. By the way this is only a slight ramble, because in my current circumstances the stress and “disintegration” are REAL.

    This series has been fascinating and has answered a lot of my questions- this has been the missing piece. I used to wonder if it was possible to switch types as you mature, but now I’m seeing that I switched attitudes in many of my functions (mostly from analytic to holistic) when entering parenthood.

    The description in this episode of the way the Ti types argue nailed it for me- it sounded like every argument ever between my husband (ISTP/analytic Ti) and me (INFJ/holistic Ti).

    Two comments:

    1) I think it might be common for people to have their second function as their most balanced as it’s often the one we’re most conscious of using.

    2) Wholistic introverted thinking totally has an expertise: it’s finding the flaw in every model it uses and introducing uncertainty. If someone ever listens to your whole speech on a soap box and then slowly walks you through your own ideas showing you where they are unstable, you may have met a wholistic introverted thinking user.
