Knowledge provides power and competitive advantages, especially in business. Having knowledge about products, customers, operations, and sales processes allows companies to develop stronger products, convince customers, run efficiently, and outperform competitors. It also benefits individuals by helping them pass tests, get hired, and avoid issues caused by a lack of knowledge like frequent job changes. To systematically gain knowledge, one should be aware of problems or deficiencies, thoroughly research potential solutions, analyze data, draw conclusions, and implement strategies. Presenting knowledge requires humility, experience with the topic, and disciplined study rather than just verbose blustering which others can see through.
