Instead think deeply about what you have—the tools and materials you will be working with. Ground yourself not in dreams and plans but in reality: think of your own skills, any political advantage you might have, the morale of your troops, how creatively you can use the means at your disposal. Then, out of that process, let your plans and goals blossom. Not only will your strategies be more realistic, they will be more inventive and forceful. Dreaming first of what you want and then trying to find the means to reach it is a recipe for exhaustion, waste, and defeat.
