Leverage a principle from Peter Drucker: identify categorical decisions that eliminate entire classes of future choices. Instead of managing countless small decisions, make one sweeping rule (e.g., no new books, no public speaking for a year). This single choice removes thousands of subsequent decisions, creating massive mental space and clarity.

To maintain performance over the long term, Canva's CEO deliberately creates strict boundaries between work and life. By removing email from her phone, she can be "all in" when working at her laptop and "all out" when she's not, allowing for true mental separation and recovery.

Your brain can only hold about seven 'attention units' at once. Every incomplete task, messy desk, or unresolved conflict occupies one of these slots. Systematically 'cleaning up messes'—both physical and relational—frees up mental bandwidth, allowing you to focus on high-priority work.

True rest requires a mental break, not just a physical one. Use a technique called "noting" to detach from stress-inducing thought loops. When you catch your mind spiraling—even while physically resting—simply label the activity: "worrying," "planning," or "comparing." This act of observation creates distance, helping you step away from the story and return to the present moment.

Using 'unread' emails as a to-do list creates a tedious ritual of re-opening and re-marking messages. A more efficient system is to treat the entire inbox as the to-do list and archive emails immediately once they are handled. This eliminates the need to maintain 'unread' status and simplifies your workflow.

To remain effective, it's crucial to manage information consumption. The goal is to be aware of world events without drowning in them to the point of paralysis. Tools that create friction, like app blockers, can help maintain this balance and preserve the mental capacity for meaningful action.

Feeling "off the clock" requires rigorous upfront planning. The people who feel most relaxed about their time are those who have meticulously managed their schedules, removing the background anxiety of pending tasks. Discipline is the prerequisite for freedom, not its opposite.

At scale, the biggest threat isn't a lack of opportunity but mental overload. The key is to treat your focus as a finite resource and actively protect it. This means becoming comfortable saying "I'm done for today" and disappointing people, realizing that protecting your mind is more strategic than satisfying every request.

Anxiety spikes when you mentally separate from your own capacity to handle future challenges. Instead of focusing on uncontrollable 'what ifs,' the antidote is to reconnect with your agency and ability to respond, regardless of the outcome. Doubling down on your capacity to handle things quiets the alarm.
