To do well in business you need to have an edge. This means you need to be active and awake. Naturally curious people make great business people because they take an interest in the world around them. They are always on the look out for new experiences and trends.
Edge doesn't always come from concentrating on business topics. Truly transformational breakthroughs come at the interfaces between different groupings. Between science and the arts, religion and business, technology and craft. Don't be afraid to extend the boundaries of your knowledge. Who knows what you will find.
