Ten tactics that have survived scrutiny from the founders who actually use them. Some are counterintuitive; all are tested.

1. The 15-minute cost rule

Any recurring task taking >15 minutes weekly is a delegation or automation candidate. Not someday — this quarter.

2. The "tomorrow tomorrow" rule

Anything that can wait 48 hours should. Most urgency is manufactured; 48-hour gates reveal which things actually needed your attention today.

3. Two inboxes, not one

Separate email address for marketing / newsletters / transactional. Primary inbox is humans only. Cognitive load drops by half.

4. Office hours instead of DMs

One or two weekly slots for team questions. Reduces the drip- interruption pattern that kills deep work.

5. The Sunday 30-minute review

Not strategy — logistics. Calendar, priorities, what's in motion. Thirty minutes Sunday evening means Monday starts clean.

6. Standing or walking calls

Most internal calls can be walking calls. Different cognition happens on feet than in chairs; people are also usually more direct when walking.

7. The "I'll think about it overnight" default

Never commit to a meaningful request in the meeting. "Let me think about it overnight" is always available and always defensible.

8. One context-switching day per week

Pick one day for meetings and admin. The other four become deep-work days. Mostly-continuous blocks produce disproportionate output.

9. Email templates for the five things you type weekly

Intro emails. Sales follow-ups. Decline-politely. Ask-for-intro. Meeting-prep questions. Saved templates in your email client save 30+ minutes a week indefinitely.

10. The "three sentences" email rule

Any email you're composing longer than three sentences — ask yourself if it should be a doc or a call instead. Most over-long emails don't actually communicate better; they just take longer.

None of these are productivity theatre. The founders who use them look calm while the ones who don't look busy — and calm ships more, eventually.
