That's funny. For many years I defended that fear is the original feeling! All other feelings can be dissected back to fear..
It was mostly a pet project I would entertain in my mind with when I was bored, the way some people will sing a song in their heads while doing dishedhe dishes or laundry! (Yes, I'm weird! No, it's not the weirdest I can be!)
But like you mention, the more you think about it and the more your perspective seems blinded by it.. It was when I noticed how fearful I actually was (even though I acted - and still do - tough!), that I've tried seeing the world with new eyes.. it helped to surround myself with people that thought differently and challenged me. But new surroundings, better stories and challenges mean nothing, if we're not willing to admit we were wrong, and pivot to a new perspective..
