Shana,
Passion is the power that fuels us. Passion is vital to grind out the day to day of a long-term goal or project, especially in light of others that say it can not be done. You will fail as an entrepreneur if you have no passion.
However, without vision, passion is the proverbial bull in the china shop. The nightmare of undirected or worse misdirected energy.
And without action, even a great vision and fantastic passion will end up as an unrealized daydream. I know so many passionate visionaries, who failed because they never got their vision on the ground …
You need all three to make it happen: vision - passion - action. Miss one and you are going to fail.
(I gave a TEDx talk on this called the "Art of Changning Minds" :)
And prosperity is not something I chase, so my definition of it is irrelevant.
My passion is much more along these lines: I want to change minds, create joy and make a real difference in people's lives and that often requires putting yourself or your health at risk, doing what others consider to be risky and unsettling. It means being willing to live in places where you can't enjoy your surroundings, because of the circumstances that others have to endure day in and day out. To top it all off, it often entails denying yourself creature comforts, at least for a time to fulfill your vision.
That's where I experience the most joy and a kind of spiritual prosperity (if you want to call it that), but it's definitely not a physical one.
And I'm okay with that.
