This quote, “The first rule of business is: Do other men for they would do you,” is essentially a twist on the Golden Rule, which holds that one should treat others as one would like to be treated oneself. However, Dickens’ version is more cynical and pragmatic, suggesting a dog-eat-dog world where everyone is out for their own interests.

In this context, the quote implies that in business, one should anticipate the moves of others based on the assumption that they are driven by self-interest, just as you are. It suggests that to succeed, one must stay ahead of the competition, potentially by employing the same tactics they would use against you.

Applying this idea to today’s world, it could be interpreted as a call for strategic thinking and competitive intelligence. In a rapidly evolving business landscape, companies need to stay abreast of their competitors’ strategies and be ready to counteract them effectively. It may also imply the importance of safeguarding one’s own business interests and intellectual property.

From a personal development perspective, this quote could be seen as a reminder to be aware of the motivations of others, to be assertive in pursuing one’s own goals, and to not be naive about the potential for exploitation in various aspects of life. However, it’s also crucial to balance this approach with ethical considerations, as success achieved at the expense of others can often lead to negative consequences.
