I'm almost 40. I hear that physical changes happen "all of a sudden" when one hits 40, so I don't know what's in store. I think I look *a little* younger than I am (I have been assumed to be the younger sister before.)
Inside, I still feel like a teenager and I like it that way. I feel like I am "in touch" with my inner child, with all the wide-eyed amazement, adventurous spirit, and passionate feelings. The one thing that has changed the most over the years is my anxiety has lessened, which I feel like helps me to better tap into those good things of having a younger spirit, more so than when I was actually that age.
I am definitely more adventurous than most people my age.
I have a lot of "grown up" skills, but still have problems with things I have ALWAYS had problems with, like organizing and keeping track of stuff. I still forget appointments, pay bills late, have trouble with changes in my weekly routine, lock myself (and the kids) out of the house, forget my phone, my house is in disarray (not the worst I've ever seen, but not as good as what's considered "normal".) I'm not sure I would ever get good at these things without an assistant. I really need a personal secretary, if I could only afford one.
I have gotten a lot better at emotional control. Basically now, I know most of my triggers and signs that I am getting overwhelmed and can get out of the situation before I blow up. However, I still have *VERY* intense feelings. I have learned better how to CHANNEL them so they can be put to good use. I wouldn't trade having these intense feelings, but it's better to control them properly. They make me feel alive.
