What we choose to focus on and what we choose to ignore plays in defining the quality of our life.
Newport sharpens what Hill implied. Focus and ignore are the same decision from opposite sides — and the modern environment has made the ignoring almost impossible.

This is Cal Newport, not Napoleon Hill. The site has a lot of Hill quotes; this one is a contemporary voice making a related claim from a different angle.
The Newport version of the principle
Hill spent most of his attention on what you choose to focus on — desire, definite aim, belief, persistence. Newport adds the other half explicitly: what you ignore matters as much as what you focus on. They’re not separate decisions. They’re the same decision made from opposite sides.
Newport’s work — Deep Work, Digital Minimalism, A World Without Email — is essentially an extended argument that the modern environment is designed to make ignoring things almost impossible. Notifications, feeds, group chats, the ambient pull of small dopamine. The result is that attention, the resource everyone needs to do real work, has become scarce in a way it wasn’t fifty years ago.
The quality-of-life claim is downstream. If your attention is fragmented across whatever the algorithm decided you should care about today, the life you build is also fragmented. The opposite is also true.
What I keep seeing in mastermind rooms
The members who run their attention deliberately — who have actually decided what they’re ignoring — show up to the room with sharper progress on fewer things. The members who haven’t show up busy, exhausted, and stuck. Same number of hours; very different output.
The room can help with this in a specific way. When you commit to a goal publicly, you also implicitly commit to ignoring the things that compete with it. The room remembers what you said you were focused on; it notices when you’ve quietly drifted into something else.
Where this sits in the method
This sits at the intersection of Mindset (Pillar 1) and Planning & Goals (Pillar 2) in the Mastery Method. It’s also why Systems & Automation (Pillar 3) matters more in 2025 than it did in 1937 — the systems are how you make the ignoring durable rather than constantly relitigated.
Hill knew it. Newport sharpens it. Quality of life is built out of attention, and attention is mostly subtraction.
