Book Recommendation: “The Great Mental Models Volume 2” by Shane Parrish

Understanding systemic thinking improves long-term decision-making in business and wealth planning.

Complex decisions rarely exist in isolation. They sit within systems, interconnected variables that influence outcomes in ways that are not always immediately visible.

“The Great Mental Models Volume 2” explores this concept through the lens of systems thinking. Rather than focusing on individual decisions, it examines how those decisions interact within broader frameworks.

For business owners and investors, this perspective is particularly valuable.

Financial planning, business growth, and wealth preservation are all system-dependent. Changes in one area, tax strategy, asset allocation, or operational structure, have ripple effects across the entire landscape.

This often means that isolated decisions create unintended consequences.

The book introduces models that help identify these interactions. Feedback loops, bottlenecks, and compounding effects are explored in a way that translates directly into practical thinking.

In estate planning, this approach shifts the focus from individual actions to overall structure.

For example, transferring wealth is not just a legal or financial decision. It affects family dynamics, business continuity, and long-term control. Viewing this as a system highlights dependencies that might otherwise be overlooked.

This leads to more robust planning.

Another relevant concept is second-order thinking, considering not just the immediate outcome of a decision, but its subsequent effects. In wealth planning, this is critical.

A tax-efficient move today may create constraints tomorrow. A business decision that increases short-term value may reduce long-term flexibility.

Understanding these trade-offs improves decision quality.

The strength of the book lies in its ability to make abstract concepts actionable. It does not provide prescriptive advice, but frameworks that enhance thinking.

This aligns closely with high-level advisory work.

Clients rarely need more information. They need better ways to interpret it.

Systems thinking provides that lens.

It encourages a shift from reactive decisions to deliberate strategy, considering not just what works now, but what sustains over time.

Because ultimately, wealth is not built or preserved through isolated actions.

It is managed through systems.

Client Testimonial

“Having seen John of Legacy Wills present at a property event, it was clear he had both the breadth of knowledge and experience and also the ability to make a very dry subject both understandable and engaging. That’s a tough call when talking about Wills, Trusts and death. John produced Wills and POA’s for myself and my wife in a timely, effective and reasonable manner. I have subsequently recommended him to numerous colleagues and friends to cut out the jargon and challenges surrounding this critical protection, which is too often deferred or neglected.”
