People matter
Business is all about the ways in which people work. How they work with information, ideas, and tools. Above all, how they work with each other. When we talk about finance, strategy, or the other "hard" elements of business, it is people who ultimately perform these tasks.
Quite simply, people matter. When good people use the right tools and knowledge in the right way, and work together effectively, outstanding results are achieved. To excel in business, you must always involve and deal effectively with people.
