Welcome to Models That Matter – where thinking better begins.
Ever wondered why smart people sometimes make poor decisions? Or why some strategies succeed while others fail despite similar resources?
The answer often lies not in what we know, but how we think.
At Models That Matter, we explore timeless mental models — the powerful thinking frameworks used by the world’s best decision-makers, innovators, investors, and leaders. These aren’t just concepts for academics or CEOs. They’re practical tools you can use every day — in your career, business, relationships, and personal growth.
What Are Mental Models?
Mental models are the lenses through which we interpret the world. They help us make sense of complexity, avoid blind spots, and approach problems with clarity and precision. From Inversion Thinking to First Principles, from Second-Order Effects to the 80/20 Rule — these models are shortcuts to sharper insight and wiser action.
About Me
Hi, I’m Sushil Kumar, a lifelong learner, digital strategist, and passionate advocate of clear thinking.
After spending over a decade working with leaders across industries — from technology to healthcare — I realized that the most successful people don’t just work harder; they think differently. They consistently apply better mental models to solve problems, seize opportunities, and build systems that work.
I started Models That Matter to share those tools with anyone who wants to improve how they think, decide, and lead.
Whether you're a student trying to navigate life, a founder scaling your startup, or a manager making critical choices under uncertainty — you’ll find something here to help you think clearer and act smarter.
