Great leaders are tested and tried in many ways. They persevere through trials and develop the ability to weather tough storms. Calvin Coolidge, 30th US President, summed it up nicely:
Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost proverb. Education will not; the world is full of educated derelicts. Persistence and determination alone are omnipotent.
Success comes from developing and perfecting persistence and determination.
As a side note, I found an interesting (and somewhat related) article contrasting two of pro basketball’s biggest stars: Kobe vs. Lebron: how leadership trumps likeability. It brings out the importance of persistence in leading teams as a player.
The Product Management Perspective: The importance of persistence in creating great products cannot be overstated. Things do not always go as planned. Great product managers learn from past mistakes and continue to press forward regardless of the obstacles they face. Product success does not come overnight, but instead comes over time, though consistent application of sound principles.
