Frequently asked questions
How many hours of deep work can a person actually do per day?
Research suggests most people can sustain 3 to 4 hours of genuine deep work per day. However, the average self-employed professional gets only 1 to 2 hours of uninterrupted focus because meetings, communication, and admin fragment the day. This assessment measures your actual number, not the theoretical maximum.
What counts as deep work?
Cognitively demanding work performed in distraction-free concentration. Client strategy, complex writing, coding, creative design, and difficult problem-solving qualify. Email, Slack, routine meetings, admin, and any task you can do while distracted do not. The distinction is cognitive demand and focus quality, not difficulty.
Why do most people overestimate their deep work hours?
Because they count the blocks on their calendar, not the actual uninterrupted time within those blocks. A 2-hour "deep work" block interrupted by 3 Slack messages and a calendar check delivers about 45 minutes of actual deep focus. The assessment measures interruption frequency and recovery time to calculate your real capacity.
How can I increase my deep work capacity?
Three highest-impact changes: protect deep work blocks by closing all communication channels, schedule deep work during peak energy hours (morning for most), and batch meetings onto fewer days so you have entire mornings without interruptions. The assessment results point you to the specific change that will help most.
Does deep work capacity change over time?
Yes. Deep work is a skill that improves with practice. Professionals who consistently protect 2-3 hours daily report increased capacity over 4 to 8 weeks. The reverse is also true -- fragmented schedules atrophy your ability to sustain focus. Retake the assessment monthly to track your trajectory.
