Yes, it all lies within. Our best leader is within. Our Intuition. Our Intuition sees what lies without the eye, while our ego only sees what lies within the eye.
Yes those are "leading the pack who are doing their thing". As always, because their main focus is on the Heart, allowing for 100% creative leverage in the Now.
