Habit tune-up: deep work, email overload, and project sequencing

Executive overview

Working from home collapses the boundary between work and rest, making deep work harder to sustain. Academia's unregulated email culture systematically privileges the unpleasant and penalises caregivers. Project sequencing matters less than people think — natural preference beats any fixed rule.

The real enemy of deep work is not distraction but a failure to design your environment and schedule to support concentration.

Doing deep work when home and office share the same space

• Leave the house to do deep work — parks, outdoor cafes, trails with a hotspot.
• Productive meditation: work on a single problem mentally while walking; focus returns with practice.
• "Adventure studying" — novel locations restore cognitive excitement and reset focus.
• Time-block plan every minute: label work periods, project slots, and a firm stop time.
• Replicate Darwin's sand walk: a fixed pre-work route conditions the brain to shift into deep-work mode.
• Lockdown mentality (refusing to leave home) is a psychological habit, not a health requirement — lose it.

Diagnosing and fixing afternoon energy crashes

• A three-hour afternoon nap signals an underlying problem, not a habit to guilt-manage.
• Rule out hypersomnia linked to depression — most universities offer remote mental health support.
• Poor sleep is the most common culprit; keep the phone out of the bedroom entirely.
• Automate all food and drink choices from waking until dinner — optimise for steady energy, not variety.
• If the home is noisy, get outside; if that's impossible, use large over-ear headphones with non-lyrical music repeated until it fades to background.

Academia's email problem and what to fix it

• Professors face unchecked, unsupervised, and inequitable demands on their time from dozens of units simultaneously.
• The current system accidentally rewards the unpleasant (à la Feynman) and punishes caregivers who can't offset overload with early-morning or late-night hours.
• Fix requires top-down commitment: universities should be "citadels of concentration," working backwards from the goal of cognitive output.
• Service transparency: make contractual service hours explicit and visible; any request beyond the limit requires dean-level sign-off.
• Back pressure is good — if only five of twenty-five requests can be serviced, that forces units to rethink whether the work is necessary.

Going back to school as an adult

• Adults outperform traditional undergraduates because they treat coursework as a job: scheduled, planned, no wasted time.
• Banish the word "studying" — always specify the exact activity (e.g., active recall with index cards).
• Apply criticality after every graded piece: what worked, what would you skip, what would you spend more time on? Iterate until your methods are far ahead of peers.
• Treat time as constrained even when it isn't — structure produces better outcomes than freedom.

Sequencing multiple concurrent projects

• Break each project into milestones averaging one week; this is the unit of work to sequence or parallelise.
• Sequential (finish one milestone before starting another) and parallel (split hours or days across projects) have no intrinsic productivity difference.
• Choose whichever feels more natural — the advantage comes from going deeper, not from the scheduling pattern itself.
• Parallel tracks are easier when subject matter is very different; cognitively distinct work draws on separate resources and reduces switching cost.
• Keep parallel tracks sequential internally: finish the chapter, then write the article, then return to the chapter.
• Avoid open-ended milestones — if "completion" is six months away, the chunk is too large.
