One minute you're solving a technical bug; the next, you're pitching to investors or onboarding your fifth hire in as many weeks. Founders often tell me, “Every day is chaos, I just need to survive the week.” But that survival mode comes at a cost: strategic work gets buried, decisions drag, and your tempo becomes reactive instead of deliberate.

This column is about changing that. Because if you're not designing your week, someone else is. And if every meeting is “urgent,” your mission-critical work, such as setting strategy, building culture, and carving a path through uncertainty, gets lost in the firefight.

The biggest mistake I’ve seen startups make? Rapid growth without structure.

Structure can feel overly corporate and unnecessary. After all, part of the magic of the startup world is the agility, the chaos, the comradery that comes from scrappily building the next unicorn. But a little bit of structure, in the right way, will mean you can rapidly grow on concrete foundations rather than on sand. Don’t fall into the typical trap of rapid unstable growth which inevitably leads to redundancies later down the line.

Let’s take your diary from chaos to clarity with a neuroscience-backed calendar blueprint that helps you protect deep work, reduce decision fatigue, and lead with focus.

Why your brain hates context switching

Startups demand agility, but your prefrontal cortex wasn’t built for tab-hopping chaos. Every time you jump between tasks, Slack to Notion to Zoom to WhatsApp, you pay a cognitive switching tax. Researchers estimate it can take up to 23 minutes to refocus after a distraction, and frequent context switching significantly reduces working memory and goal maintenance capacity.

What’s worse is that decision-making quality declines with each switch. The brain's executive function wears down, making you more likely to default to easy choices, delay hard ones, or skip them altogether.

That’s why we start with the non-negotiable: carving protected blocks for deep work, the kind that moves the needle.

The 3-part calendar architecture every founder needs

Instead of seeing your week as a random scatter of calls and to-dos, begin with three layers:

1. Deep work anchors (strategy)

Block 2–3 x 90-minute sessions per week (ideally morning) for cognitively demanding tasks: product design, investor narratives, roadmap planning. No meetings. No notifications. Just focused thought. Your brain’s “attentional bandwidth” peaks when it's uninterrupted.

2. Firefighting windows (operations)

Contain reactive work, Slack replies, bug triage, rapid hiring pivots, into 1–2 daily windows. Time-box them like meetings. This limits the sprawl and keeps your day from being consumed by the loudest voice in the inbox.

3. Cadence meetings (team)

For sub-15-person teams, meeting overload is often self-inflicted. Institute strict hygiene:

• Daily Stand-Up (15 mins max)
• Weekly Retro/Planning (45 mins)
• Founder 1:1s (25 mins fortnightly)

Add constraints: no meetings before 10am or after 4pm. Parkinson’s Law tells us work expands to fill time, we can flip that.

It may feel uneasy, or even insurmountable, to implement this entirely initially. Play around with making it work for your calendar, such as reducing the deep work time from 90  minutes to 45 minutes initially, but do challenge yourself to jump in and give your calendar this overhaul. It will pay dividends!

Single-tasking isn’t a luxury, it’s a performance edge

Multitasking feels productive but it’s a cognitive illusion. Neuroimaging shows that the brain doesn’t truly parallel process complex tasks; it toggles rapidly between them, burning mental energy and increasing error rates.

The fix? Themed days or half-days. For example:

• Monday AM: Strategy deep work
• Tuesday: Team meetings + 1:1s
• Wednesday: External calls + pitch prep

This clustering reduces task-switching and builds neural efficiency, helping your brain stay “in state” longer.

Bonus: it also helps your team know when and how to reach you, making your time predictable, not chaotic.

Tactical tools to stay on track

Even the best-planned week needs friction-reducing tools to maintain discipline. Try these:

• Calendar labels: use emojis or colour-coding to visually separate strategy, meetings, ops
• Email delay tools: utilise your email’s Send Later function to help you avoid the reactive ping-pong
• “Pre-mortem Fridays”: 20 minutes to ask, “What would make next week fail?” This primes your prefrontal cortex for proactive planning

Your energy sets the company’s tempo

Here’s the part most founders miss: your calendar isn’t just about efficiency, it’s culture-setting. If you’re in back-to-back calls, your team mirrors that pace. If you respect focus time, they will too.

Instead of romanticising burnout as a badge of honour, model what sustainable speed looks like. Embed “think time” in your week. Design your diary like it’s a product. Ask: does every block add value? Does this meeting have an agenda? Do I leave space to breathe?

Because time isn’t just money in startups, it’s your edge.

• TL;DR: your weekly CEO blueprint
• 3 x Deep Work blocks (90 mins, AMs)
• 2 x Ops windows (inbox/Slack triage)
• Clear team cadence (brief, structured meetings)
• Single-task via themed blocks or days
• Review on Fridays (what worked, what didn’t)

Your calendar is more than a record of what happened, it’s a tool for what’s possible. Build one that fuels strategy, not just survival.
