Adopted from the following great insight shared by Simon Sinek from his book Start With Why
Wright Brothers as we all know invented the first airplane.
But if we look book at history we can find that Samuel Langley was more equipped than the Wright Brothers , yet could not achieve what the Wright Brothers did.
Langley had a passion for aeronautics and knew WHAT he needed to do.He did not have a CAUSE to champion and more than anything else fame , earning money was his driving motivation.There was no clear sense of WHY.
Contrast this with the Wright Brothers , they clearly knew WHY it was important to build the plane.Not a single person working with the Wright Brothers had college education.
They imagined the benefits to everyone else if they were successful , they had the clear sense of WHY.Rest as they say is history.
