Many professionals boast about working long hours, but this time is often filled with distractions and low-impact tasks. The focus should be on eliminating "whack hours"—unproductive time spent doom-scrolling or in pointless meetings—and working with deep focus when you're on the clock.

Managers work in small time blocks, so a meeting is just one of many. Makers require large, uninterrupted chunks. A single meeting breaks a large block into two unusable smaller ones, effectively destroying an entire half-day's worth of productive output for the maker.

Not all hours are equal; a 9 AM Monday slot might be worth $500/hour in focused output, while a 4 PM Friday slot is worth $10. Identify your peak performance times for deep, creative work and relegate low-cognitive tasks like watching informational videos to low-energy periods like a commute.

Mastering generative AI requires more than carving out an hour for thinking. It demands large, uninterrupted blocks of time for experimentation and play. Tavel restructured her schedule to dedicate entire days (like Mondays) to this deep work, a practice contrary to the typical high-velocity, meeting-driven VC calendar.

High-volume creative work, like writing five novels a year, isn't about marathon sessions. It's about breaking large goals into small daily chunks (e.g., three 800-word scenes) and executing them consistently in short, 20-30 minute focused blocks of time.

Productive teams need to schedule three distinct types of time. Beyond solo deep work and structured meetings, they must carve out 'fluid collaboration' blocks. These are for unstructured, creative work like brainstorming or pair programming, which are distinct from formal, agenda-led meetings and crucial for innovation.

Structure habits around your biology. Phase 1 (0-8 hrs awake): High dopamine/adrenaline; ideal for high-friction habits requiring focus and effort. Phase 2 (9-15 hrs): Rising serotonin; better for calmer, low-friction activities. Phase 3 (16-24 hrs): Sleep; crucial for habit consolidation.

Counter to popular productivity advice, many routine work tasks do not require deep, undivided focus. The key skill is not avoiding multitasking but discerning which rare activities demand full attention versus the many that can be handled concurrently. Your brain is powerful enough to manage this cognitive load effectively.

'Strict productivity' for a founder is work centered on the startup's single biggest bottleneck, approached with a direct strategy, and executed with intense focus ('goblin mode'). Any other activity, from pitch competitions to unfocused work on non-bottlenecks, should be considered 'performative' and a distraction from making real progress.
