I don't think I need to say anything about this most remarkable man through whose initial research we have satellite communication.
The first of his books I can remember reading is Childhood's End.
The only way to discover the limits of the possible is to go beyond them into the impossible.
We can become complacent, don't you think? Comfortable in what we know as possible. We can become convinced there is only this way or that way and we can become stuck. Thank goodness there are people out there who routinely open up the boxes we live in and let in the sunlight, else we might all stagnate and sink into the mud of our mundane lives and disappear entirely.
I personally am stretching the limits of what I know with my mentorship with Angela at The Bookshelf Muse. She has cast all sorts of light all over my manuscript, lighting up corners and cracks, exposing all sorts of minor and major flaws. I can't say it's easy, because it isn't. I've never done this kind of intense rewrite/revision before. As difficult as it sometimes gets for me, it's a good thing. I am pushing limits, expanding, stepping out of the box and in the process learning it isn't impossible after all.
What limits have you explored lately? What possibilities have you found in the impossible?
