conceivability, possibility and actuality

As we race headlong into this new century the world is a whirlwind of new possibilities, revelations and knowledge, but also of age-old problems, conceits and greed. It can be exhilirating and depressing, almost simultaneously. Today I ran across a nice quote at the foward-thinking site WorldChanging:

It's the widening gap between what's conceivable and what we're doing that's sometimes discouraging. It's the narrowing gap between what's conceivable and what's possible that's sometimes electrifying.

That sums it up nicely. Although I would change the first sentence to "It's the widening gap between what's possible and what we're doing that's sometimes discouraging."
