Watched a fantastic foreign film recently by the same name. The essence was there is a rainbow in the sky every single day but it is only visible when it rains; As a man of science I know it is the dispersion of light from the moisture (light refraction) in the air right after the rains that makes the colors visible.
Leadership is much like that!
It is the ability to draw images in sand and then bring them to life; it is the ability to identify talent and develop it; it is the ability to align people, resources against opportunities that will take organizations to the next level!
Yes, it is not much different from moving the prism and place it at the right angle against white light to bring out the colors to the fullest and the best!
