One of the modern problems is the obsolescence of knowledge and skills. Just 50 years ago, to be a specialist, you had to work for years; you probably heard about the 10,000-hour rule - that’s how much time it takes to become a professional in your field. Knowledge and skills were reliable strategic resources for a person - he could receive a decent salary and not worry about the future. Nowadays, skills become obsolete even before they can be mastered. What knowledge remains relevant today? Those that allow you to understand what is happening now and how it affects the future, what can and should be changed to achieve your goals. You will learn from this by mastering the "Chain ++" model.
