In Lao Tsu Sun Tzu's "The Art of War", he speaks of force, momentum, inertia and control. While the book's context is warfare, it can, and has been read and applied to many different things, including business strategy. (Thinking about it, it can apply to any human activity, as action requires all four...)
Here is my attempt at applying these four concepts, through the metaphor of snowboarding, to the task of entrepreneurship. Bear with me: I have been a snowboarder for fifteen years and have negotiated all sorts of terrain, plowed through every condition, pulled every trick; I have yet to be an entrepreneur.
You are control
You are the heart and mind of the enterprise. You have the vision and the desire which drives this excursion. You will choose the mountain, the slope and the line. You will acquire the equipment and learn how to use it.
Your body is your team. You must be in tune with it's abilities and limitations. You must treat it with respect, keep it fit, master it, know when to push it hard and when to let it rest. Listen to everything it tells you. Set goals for your body and trust it to pull you through.
Height & inclination: investment & return.
The higher the mountain, the greater the investment, the force required to acquire momentum potential. Either you hike it yourself: strain your body with time and effort, or you buy a lift ticket; financial investment. Divest some of your value for a quick lift. A wise investor will consider your strength, the height of the mountain you wish to ride, your abilities...
All your body's hard work to get you to the mountain, your investors to get you up it... a buildup of effort waiting to be released. Once at the top of the slope, your potential is quantified: force. How high? How steep? How tuned is your board? How strong your body? Are you ready to drop in? What's your first turn? Your first trick? The force of gravity is pulling you, your body makes a little hop forward, your investors another little push from behind. Ready? Here we go!
The "idea"
In all of this, the "idea" is merely that first little spark you have that morning, as you open your eyes and think: "Hey I wanna go snowboarding today." That's all. It tells you nothing of your stretches, the drive, the ticket price, the conditions, which mountain or which trails you'll ride. It doesn't tell you if you'll land that 540 rodeo flip, or if you'll land on yer head...
