one negative thing about imagination: it can also be used to fuel your fear. fear is the imagination of a future event that you don't want to happen. 9 out of 10 times it never happens anyway, but it is your imagination that is creating the fear, because the event hasn't happened yet. I'd guess that your imagination that creates the fear is based on some beliefs that you have somewhere in your head, maybe these beliefs are very negative, and that's why you tend to imagine the fear. i think that fear holds more people back, not the lack of imagination used to create a better future.

Just in case your other readers are genuinely interested in actively co-creating their world - and the sky is the limit - I'd like to divert your attention to Sufi mystics, for example.

There is a book that everyone interested in this should read: it's "L'imagination creatrice chez Ibn Arabi", by the great Henry Corbin. (And yes, it is available in superb translations.)

You see... when you know how to appropriately PROJECT your vision, there is no "past" or "future" that could resist it. You also ave to known where to build that vision, and whence to project it.

It's very simple, really - and yet incredible.
I mean literally in-credible for most Westerners today. (I am one, so there's hope for you, too. And no, you don't have to convert to Islam, in case anyone was wondering...

Godspeed!
