Case Study: How Shutting Down One Habit Boosted My Productivity

Sarah Chen is a 28-year-old marketing manager who changed one habit and it transformed her work life. Sarah, a common denominator among millions of professionals worldwide, constantly battled with productivity and being unable to keep up pace with the mountain of tasks that come her way every day. This demonstrates how one minor change can create a tipping point to improve her quality of life.

Sarah’s Turning Point

It didn’t happen overnight, but Sarah began by doing something as simple as changing when she checked her email. In this case study, we dive into her story, the science that backs it up, and how you can use similar strategies to level-up your productivity.

The Challenge: A Day in the Chaotic Work Life of Sarah

This is how a normal work day went for Sarah:

7:30 AM – Wakes up; immediately grabs phone to check emails
8:00 AM – Arrives at the office on edge from morning emails
8:30 AM – Starts responding to urgent messages
10:00 AM – Can finally focus on working tasks
12:00 PM – Lunch break distracted by more email checking
2:00 PM – Finds it hard to concentrate on important work projects, becoming frustrated with content framework setups for different marketing strategies, paid campaigns of customers that are converted but still below expected, meetings where laptops cannot be used

Sarah lived in what productivity experts describe as “reactive mode”: being pulled from one outside demand to another rather than focusing on her own agenda. As a result, she felt busy but not productive, overwhelmed but not accomplished.

The Breaking Point

It took three specific incidents for Sarah to realize she needed change:

1. Delayed Campaign Launch – She missed the deadline for a footage purchase due to email responses that took up her hours, piling up and preventing creative work.
2. Client Pain – One of their largest and most valuable clients mentioned in passing that it was taking too long for them to get back when they wanted something done.
3. Personal Impact – Her significant other said she was living in a permanent state of anxiety and preoccupation.

Sarah’s Productivity Metrics Before Change:

• Email-related activities: 47% of her day
• High-value creative work: 23% of her day
• Tasks supposed to take 3 hours: 6.2 hours on average

The Simple Fix: Time Blocking Your Emails

Sarah researched time management and decided to check email only during certain hours. This is what her new email schedule looked like:

• Morning Session: 9:00 – 9:30 AM
• Afternoon Session: 1:00 – 1:30 PM
• End of Day Block: 4:30 – 5:00 PM

Her email sat unopened beyond these windows. No notifications, no quick checks, no exceptions for the first 2 weeks.

Why This Habit Works

Time blocked email works because it tackles several psychological and practical hurdles:

Attention Residue: We retain some of the old task in our mind when switching from one task to another. Sarah cut down this mental interference by restricting email checks.

Flow-State Protection: Deep work needs distraction-free time. Email blocks created these safe spaces for Sarah to flow in and out of flow state.

Reduced Decision Fatigue: Constantly checking email means constant micro-decisions. Sarah saved her decision-making capacity by batching these decisions.

The Science Behind Sarah’s Success

The psychology behind why Sarah’s tiny change had such a profound impact:

Attention Restoration Theory

Shifting between tasks regularly exhausts our limited attention. Sarah found that focused blocks allowed her attention span to refresh and create better quality focus.

Implementation Intentions

Sarah succeeded with “if-then” planning: “If it’s not time for email, then I don’t check email.” This reduced decision-making overhead.

Habit Stacking

Sarah attached her new email habit to existing routines:

• Morning email after coffee
• Midday email after lunch return
• Evening email before end-of-day planning

Challenges Sarah Confronted and Overcame

Challenge 1: FOMO (Fear of Missing Out)

Problem: Sarah was concerned about missing important communications
Solution: She created notifications for key contacts about her communication hours and communicated the same to clients.

Challenge 2: Colleague Resistance

Problem: Colleagues expected her to be always available
Solution: Sarah set expectations with team members and demonstrated that work quality improved with her new routine.

Challenge 3: Breaking Old Patterns

Problem: Muscle memory had trained her to check email automatically
Solution: She moved the email app to an obscure folder and used website blockers during focus time.
