The thing with us is that, we make decisions first based on our instincts and then give a cover of logic and rationale.
This is the probably the only reason, why "Art of Listening" is so difficult to master.
Given the fact that I enter a room to listen to a person, and I am pre biased that I am correct, cause I have reasons. How will I ever learn new things?
For being a better Listener, you need to have Doubts. Doubts to entertain, some one else point of view.
Your own growth is your own personal journey and without having a doubt within, your bias will never break and you will never learn new thing.
So what is more important
Having a Strong Believe or having a doubt?
I have believed many things in different phase of my life and I had my doubts.
I would rather live with a Doubt than a firm belief.
After the secret of my Confidence is, "I am as confused as everyone else".
