It's a while since I read Helen Fischer's work, but I remember thinking ah-ha!
I love that idea of literally inventing yourself, growing new neurons. I have imagined sometimes when I'm involved in intense learning that I can hear those neurons and synapses growing by the second.
I love walking, sometimes when I go out, I don't want come back into the house, I'm enjoying being outside so much.
Ah, another great comment @shanibeer!! 💛 I can relate. Such empowering feelings - both! When neurons snap together during moments of intense learning, and long lengthy walks.
