 Good morning, John. About 15 years ago, I, for the first time, and begrudgingly, took the Myers-Briggs personality test. The idea of that specific personality test is to put you into one of two groups in four different categories. The most famous one being the first one, are you an introvert or an extrovert? Are you an I or an E? There's also how you gather information, as it's sensing or intuition. How you make decisions, thinking or feeling. And finally, do you prefer to, like, make judgment or gather more information through perceiving or prospecting? Two different P's, edit changes, so you might be, like, an ENTP or an ISFJ. At that time in my life, I had decided to hate personality tests. Like, look, a great deal of my understanding of myself was, like, you can't put this in a box. This is why I was extremely pleased when my Myers-Briggs personality type came back as XNXP. So for introvert extrovert, they couldn't classify me, I was right in the middle. And for thinking or feeling, also right in the middle. So yeah, you can't put College Hank in a box, take that, test, try to tell me that I am like anyone else. To be fair to the test, it was pretty weird. Like, I loved to, like, go to parties and dance and, like, have people looking at me, but mostly because of how scary that was. I love it in the way, like, that a parachuter loves jumping out of a plane. Like, it's an extreme sport. But wanting to not be classifiable is not why I dislike personality tests now. I have a different reason, and it's much more mild. Because I think it's extremely valuable to take some time for self-reflection and to assess ourselves and to understand ourselves and see what maybe are the right paths forward for who we are right now. But I also worry that the idea of a personality test leads to the belief that we are what we are and we will never be anything else. I just took another Myers-Briggs personality test at 16somethings.com and as I was taking the test, it became very clear to me that I've changed a lot and that, like, if I answered these questions as five years ago, Hank, I would be answering them differently. I am much more of a planner where I used to be an improviser and part of that's having a child, but part of that's having, like, a team of 15 people that are not ready for me to email them at midnight to be like, tomorrow we're gonna do this new thing! That could be frustrating for an employee, it turns out. And it turns out that I actually like working that way. It's a little less scary. And it has kind of become the default way I operate. And also now I'm not in the middle of introvert-extrovert. I am way over on the extrovert side and anybody who knows me will tell you that. So this is the time of year when people might be setting goals for how they want to behave or how they want things to go in 2018. And what that means is changing behavior. And that is frickin' hard because we emphasize these neural pathways, ways that we act, things we do with our hands, how we interact with other people, what we give value to. All those neural pathways get more and more structured and changing them gets more difficult. And I want to make the case that it really doesn't help if we believe that we were born to only ever be one way ever. We change hour to hour based on situations and we change decade to decade. Like, there's something very simple about feeling like you'll never change and about taking a test and knowing who you are, but we're not that simple. I think it's a disservice to the complexity of you. Absolutely, find ways to live that work for you and people who appreciate you for the way you are. But also know that if you want to change, you can. And even if you don't, you probably will. So if you have a moment, I have an exercise. Can you write down in the comments for all of us to read something that you changed about yourself? It can be something simple like you changed how you write A's or it can be more complicated like you decided to be the kind of person who listens more and talks less. I mean, is there somebody here who needs to take that advice? I don't know. And if you want, you can also share some of the ways that you hope to maybe change in the future because you were not carved in stone the day you were born. You are molding yourself out of clay and if you don't keep it moving, it's gonna harden up. John, I'll see you on Tuesday.
