I always focus on improving myself, and that's why I'm acually here (well that is actually more of curiosity about myself). If I had to summerize my thinking as an ENTP, it wouldn't be improvization, but aiming. I always aim to what I believe is my full potential, and self-improvement is vital part of it.
By the way, John, I find that video really fascinating. Can you direct me to where to expand upon it? (I want an honest answer from a HUMAN, not search it on Google and find that what I learned was bullshit.)
