ESTP's are high energy people.
I may or may not be an ESTP as I have trouble deciding, but I'll tell you this:
I have a ton of energy. Usually I feel awesome, I listen to epic loud music, and I drive fast (in my wrangler). Thing is, for a while now I've felt I was an introvert. I'm so high energy that I feel like I tend to run out of energy after a while. It almost feels like an energy drink crash. I'll be at my friends house surrounded by friends, and I'll be the center of attention, but after a while I just lose it and start to peter out and I won't have any energy to talk to people anymore so I'll go play video games for the rest of the night. I'll want to hang out with them, but I lose energy so fast it makes me feel introverted even though I want to still hang out with them. I still can't seem to figure out if its because I need food, or if I'm an introvert. Ideas?
