What are the key takeaways from "Think and Grow Rich" that can be applied by entrepreneurs?

A manufacturing company can apply the principle of persistence by continuously striving to improve its processes, products, and services, despite any challenges or obstacles that may arise. This could involve persisting in research and development efforts to innovate and stay competitive, maintaining quality standards even when it's difficult or costly, and persisting in efforts to train and develop employees. The company should also be persistent in its pursuit of its goals and vision, not giving up when faced with setbacks or difficulties.

Companies might face several obstacles when applying the principle of persistence from Think and Grow Rich. These could include resistance to change, lack of motivation, fear of failure, and lack of clear goals. To overcome these, companies could foster a culture of persistence by encouraging employees to embrace challenges and learn from failures. They could also provide clear goals and regular feedback to keep employees motivated and focused. Additionally, providing resources and support for employees to develop their skills and resilience could also be beneficial.
