One of the most exciting things about human beings is our ability to imagine alternative futures. We can somehow form a picture of one set of possibilities, break it down into elements, reshuffle them, and picture alternative possibilities. And then comes the interesting part. If we like one of those alternatives, we can decide to try to make it real. This might be as simple as firing off an email to invite someone to lunch to discuss the idea. Or it might mean devoting the next years of your life to create a product you believe in. Each such intentional act requires a level of determination, or the imagined future simply won’t happen. The more challenging or unlikely the possibility, the greater the determination needed. And the fire that fuels that determination is conviction.
Conviction comes about when the possible future that you see aligns with a deeply held view of how the world should be. The greater clarity you have of a possible future and the more passionate your view is of the desirability of that future, the greater your conviction will be."
