We've grown accustomed to the idea that to get an economy going you need more than tax incentives, low interest rates or quantitative easing. You need confidence.
Confidence is the yeast you add to the basic ingredients to make the bread rise. And if confidence is the magic ingredient required at the macro-economic level, its micro equivalent at the company level is energy.
You can set the perfect strategy, fine-tune your business processes and restructure every division, but without energy the whole thing risks falling flat.
