7-day reply log + weekend formula + 3 reply-handling strategies.
Core Insight
Sophie Leroy (2009) introduced the concept of “attention residue”: every switch from Task A to Task B leaves part of your focus behind—full recovery takes 20 minutes. Replying to a message mid-service isn’t 30 seconds; it’s 20 minutes of half-focus. 20 switches a day equals a full day running at 60% power. The log’s goal isn’t to track time—it’s to turn hidden costs into visible numbers.
7-Day Reply Time Log (one entry per day)
| Time Block | Reply Type | Duration | What You Were Doing | Recovery Time After Switch |
|---|---|---|---|---|
| Morning Wake-up | Accumulated “Any Availability?” × ___ messages | ___ min | (Sleep → Reply) | ___ min |
| During Service | “When’s the break?” “How long for dye?” × ___ times | ___ sec each | (Servicing client) | ___ min each |
| Lunch/Break | Slot confirmation/rescheduling × ___ messages | ___ min | (Eating/resting) | ___ min |
| Evening | Quote + back-and-forth scheduling × ___ threads | ___ min | (Housework/family time) | ___ min |
| Pre-bed Scan | Clear unreads | ___ min | (Getting ready to rest) | ___ min |
Log for one week only. Most see a pattern by Day 3: the block with the most switches is your lowest-energy window.
Weekend Calculation: Your Reply Hourly Cost
| Calculate | Formula | Your Numbers |
|---|---|---|
| Weekly Reply Time | Sum all blocks | ___ minutes |
| Switch-Residue Cost | Switches × 20 min × 50% (incomplete residue) ÷ 60 | ___ hours |
| Weekly Hidden Total Cost | Reply Time + Residue Cost | ___ hours |
| Monthly Cost (Hourly Rate Conversion) | Weekly cost × 4.3 × your hourly rate | $ ______ |
| Benchmark: Your Revenue Ceiling | If these hours were spent serving clients = how many extra slots? | ___ slots |
Typical result: solo studios spend 6–10 hours weekly on replies and residue—equivalent to surrendering 8–14 service slots each month.
3 Reply Types, 3 Handling Strategies
| Type | Weekly Share | Strategy |
|---|---|---|
| Standard-Answer Type (hours/pricing/availability) | Usually 60–80% | No need for you—fixed questions, fixed answers |
| Scheduling Type (booking/rescheduling) | Usually 15–30% | Needs “calendar view” not “your view”—open self-service slots |
| Judgment Type (special requests/complaints/complex quotes) | Usually 5–15% | Needs you—and needs you at your best |
After logging, categorize every reply into these three buckets. The first two buckets show what can be delegated.
After reviewing this, you might wonder: Who has the patience to manually log every reply all week, then crunch the numbers on Sunday?
That hesitation is the starting point of the problem.
