Well, in some ways I'm the same, but in others I'm not. I don't think it was the result of a
change so much as an "awakening" or a realization of potential, but at age 11 I experienced a "personality shift"- at least I always call it such.
I used to be a very logic-based child, inclined towards mathematics and hard science, very controlled and analytical and pretty much Obsessive Compulsive about neatness and everything being in its place. At age 11, my mind shifted, and I became the opposite - inclined towards literature, art and "soft" sciences instead of hard science and maths, more intuition based, far more relaxed. However, if I think about it, I don't see it as actually having changed who I am - I was always very imaginative and flexible in a loose, decidedly non-orderly way
internally- no matter my outward manner (I had literally hundreds of imaginary friends, although admittedly quite a few were supporting characters...). It's just that I operated inside a cage of my own mind and now I don't. I think the apparent shift was simply the result of a survival strategy. I'm very sensitive to my surroundings- sensory overload is a real problem, sometimes, and the way my memory works doesn't help. I'm convinced the reason my mind was so oddly tight, controlled and logical as a young child- and why I was so obsessed with neatness and keeping things in place- was to protect it. I needed the "shields" kept up, the control in place. If I had opened up and "been myself" at younger ages it would have destroyed me. You know like those autistic children who are really fast developers, really complex little minds, then they just suddenly lose it, shut down, even go catatonic? I was diagnosed with aspergers, but I never had any serious problems (I've always wondered why these other children, whose development histories mirror mine so closely, didn't get through it the way I did -same development rate, same milestones, same sudden drop at the same time...only I bounced back and they didn't

). Anyway, I had to maintain a tight controlled orderly mind to keep processing everything...and at about 11, my mind had grown sophisticated or powerful enough to deal with it all, and I dropped those shields and let myself be.
I actually had a powerful recurring dream that I think supports this. Throughout my childhood, I had a dream about a tsunami - I was in a bay, and trying to climb a ladder up a sheer cliff to escape. The tsunami always washed over me before I reached the top; until one time I made it. That was around about the time of the shift...so naturally I look back on that now as obvious symbolism, my mind telling itself/me/whatever that it was ready, that I could drop those barriers and open my mind without "drowning" in it all.
One of the problems of the whole thing is that it left me with a subconscious bias that I have to work to overcome - basically, that overly careful, controlled people who act too deliberately "logical" and neatly are childish and yet to "grow up", as opposed to just different. Amusingly, I assume it's the exact same bias some people have towards those who are "childish" in more regularly accepted ways- they probably consider the traits I view as "mature" childish, and those I view as childish mature.
There are a few other changes, but again at heart I think I was the same then as I am now. I've always been good with people I meet in person - good at reading them, good at seeing through them, for some reason having them like me, and yet also socially awkward and a bit infuriating to those who know me. I've always lacked any instinct for aggression, which is actually now a problem because thanks to circumstances I've wound up with a deep core of bitter anger that I don't know what to do with or how to release, because I don't have any valve for doing so. And I've always had a strong connection to the natural world- in a purely philosophical sense; don't ask me to actually
hold an animal, because I'll flinch from the budgie's punishing beak or the hamster's fearsome claws...
