In life and at work, things happen all the time. There's tension. We can’t always choose what happens, but how we react to whatever is happening, the tension, is our choice. First, there is stimulus (a nail in your foot or a business opportunity) that draws your attention. Then you assess the situation in order to understand what's going on (the nail is rusty, and it hurts a lot, or the business opportunity would position us firmly against our competition if executed on). Third, you consider what the desired position would be (no nail in the foot or market leader). Lastly, you go ahead and execute, closing the gap between current and desired position. The loop is closed, and the tension is dissolved.
