Entrepreneurs and leaders must learn a combination of these skills to have a successful organisation.

A. Understanding financial documents like balance sheets and income statements is crucial. This knowledge helps in making informed decisions about the company's financial health and future.

B. Strategic thinking, influencing people, and developing organisational systems are also vital. Strategic thinking allows leaders to plan for the future and make decisions that align with the company's goals. Influencing people is important for motivating employees and fostering a positive work environment. Developing organisational systems helps in creating efficient workflows and processes.

C. Managing technical details and using current business jargon can be beneficial. Technical knowledge can help in understanding the company's products or services better. Business jargon, when used appropriately, can facilitate communication within the industry.

D. Controlling people and manipulating organisational systems, however, is not recommended. It can lead to a toxic work environment and is not a sustainable way to run a successful organisation. Instead, leaders should focus on empowering their employees and creating systems that support their work.
