Checked 17 Oct 2026. Each line is in our own words, with where it was said and an independent study or guideline next to it. Ties: Sells his own paper Time-Block Planner.
Their own practice · His own weekly average as a professor, not a studied target. Counting the hours does help: in 138 trials, tracking progress raised goal attainment, more so when it was written down Research
Costs: a tally on paper, under a minute a day; the hours come from blocks you protect on the calendar
Habit
Shutdown ritual to end the workday: close open loops, check tomorrow, then stop
Mixed evidence · Writing a plan for unfinished tasks helped employees switch off in the evening in one experiment, mainly those who find that hard; a short “ready-to-resume” plan cut attention residue in four studies (Leroy 2018). The ritual as a whole is untested Research
Costs: no money; a few minutes at the end of the workday (he gives no length)
Mixed evidence · A 158-study meta-analysis: time management goes with better job performance (r about .25) and more so with well-being, but most studies are cross-sectional. His “40 blocked hours beat 60 unplanned” is his own estimate Research
Costs: 10 to 20 minutes a day; paper or a calendar, his own planner is optional
For your blueprint
Fixed-schedule productivity: work ends at a set time, and the work has to fit
Guideline · WHO/ILO 2021: working 55 hours a week or more caused an estimated 745,000 stroke and heart disease deaths in 2016, and output per hour flattens past a threshold (Pencavel 2014). The fixed end time itself is his method, not studied Research
Costs: no money; it forces cuts: fewer projects, more no’s (his end time is 17:30)
For your blueprint
Do fewer things at once: cap your active projects, new work waits its turn
Mixed evidence · Lab studies: switching away from an unfinished task leaves “attention residue” that lowers performance on the next one. No study tests a cap on active projects Research
Costs: no money; some no’s, and a written list of what waits
For your blueprint
Office hours: one set time a day for quick questions and back-and-forth, not all day in the inbox
Mixed evidence · Checking email three times a day lowered daily stress in a one-week trial with 124 adults; a 40-person field study found batching email did not lower stress (Mark 2016). Office hours themselves are untested Research
Costs: 60 to 90 minutes a day set aside; a note telling people when and how to reach you
Goal
Build career capital: get so good at one rare, valuable skill that you can trade it for the work you want
Mixed evidence · Believing passions are found rather than built makes people drop a new interest faster once it gets hard (O’Keefe 2018). But in a 2014 meta-analysis practice explained under 1 % of performance differences in professions, so skill-building is no guarantee Research
Costs: years of deliberate practice; he gives no timeline, so you pick the year
Habit
Landlining: at home the phone stays plugged in one spot, not in your pocket
Mixed evidence · A 22-study meta-analysis finds a small cost to attention when a phone is near, but a pre-registered replication of the best-known study found none (Ruiz Pardo 2022). Landlining itself is untested Research
Costs: no money; a charger in the kitchen or the hall
How to use this
Don't take all of it. Pick one or two lines that fit your week, try them for two weeks, and keep what works for you. That's what Vea is for: a weekly check-in that shows what each habit does for you.
Not an endorsement: these are our short summaries of what each person has published, with a link to the source. They have no connection to Vea. Ideas to try, not medical advice. On this list and want off? [email protected]
