The Danger of the \"Good Enough\" List: How Karen Reclaimed Her Brain After Chemo
The Kitchen Table
The kitchen table was buried under paper. On one side sat the "others" pile: a permission slip for her son's field trip, a volunteer schedule for the food pantry, an estate plan her sister asked her to review. On the other side sat the "Karen" pile: a journal she meant to write in, physical therapy exercises she kept skipping, a brochure for a pottery retreat she'd wanted to join for three years.
Karen stared at the mess, feeling a familiar fog settle in. Her doctors called it post-chemotherapy cognitive impairment. She called it chemo brain.
Before treatment, Karen could organize a fundraiser while cooking dinner and balancing her checkbook. Now, finding the right word felt like fishing for keys in muddy water. Focus wasn't just difficult, it was physically exhausting.
The Trap of the Endless List
For months, Karen coped by writing everything down, hoping her tired brain wouldn't have to hold it all in memory. It backfired. Every morning she faced 25 items, and because her brain was tired, she gravitated toward whatever made the loudest noise: the deadline due tomorrow, the favor she didn't want to let someone down on. Her own goals sat untouched at the bottom of the page, waiting for a quiet moment that never came.
One Tuesday, she sat down to finally look into the pottery retreat. Two minutes in, her phone buzzed with a neighbor's question. Then an email about a bake sale. An hour later she closed her laptop, exhausted, having never looked at the retreat schedule. She'd paid the switching cost of jumping between other people's priorities and her own, and she had nothing left over.
The Two-List Method
That evening, Karen tried a modified version of a well-known prioritization framework: write down everything, then choose only what truly matters.
Step 1, the brain dump. She wrote down the 25 things she felt she "had" to do that month.
Step 2, the ruthless circle. She circled only 5 items, with a rule that at least 3 had to be for her own health and recovery.
Step 3, the danger zone. Everything else went on a second list, not a someday list, but an avoid-at-all-cost list.
List A held her physical therapy, the pottery retreat registration, her oncology follow-up, her son's school forms, and her sister's estate plan review. List B held everything else, including the food pantry shift she'd normally say yes to without thinking.
The Hardest Lesson
The next day, the food pantry coordinator called asking her to cover an extra shift. Old Karen would have said yes immediately. New Karen looked at her list. The food pantry was on List B.
"I can't do it this week," she said, gently but firmly.
Her heart raced a little after she hung up. Then something shifted: the fog cleared, just slightly. By saying no to something good for someone else, she'd protected a pocket of energy for herself. That afternoon she finished her physical therapy exercises and registered for the pottery retreat.
Building Your Own List
You don't need chemo brain to feel this kind of overload. Anyone managing a demanding season can use the same structure.
Write down your top 20 current obligations. Circle the 5 that will actually improve your health, your life, or your work. Put the other 15 on a strict no-fly list until the top 5 are handled.
It won't feel comfortable the first time you say no to something reasonable. That discomfort is the method working, not a sign you're doing it wrong.
✅ Your Action Checklist
- Write down everything you feel you "have to" do this month, without editing yet
- Circle only 5 items, and require at least 3 of them to be for your own health or recovery
- Put everything else on a strict "avoid for now" list
- When a new request comes in, check it against that list before saying yes
- Notice how it feels the first time you say no to something reasonable in order to protect your own 5
🧠 Quick Facts
- Post-chemotherapy cognitive impairment, "chemo brain," makes multitasking dramatically more expensive than it used to be
- Long to-do lists tend to pull attention toward whatever's loudest, not what matters most
- Every switch between unrelated tasks carries a mental cost that compounds across a day
- A hard cap on your list, not a longer one, is often what actually protects your energy
🔬 What the Research Says
Task-switching carries a measurable cognitive cost, and that cost rises sharply for anyone managing post-chemotherapy cognitive impairment, sleep deprivation, or executive dysfunction. Structured prioritization, capping the number of active commitments rather than trying to hold everything, consistently reduces the mental fatigue that comes from constant switching between unrelated demands.
❤️ You're Not Alone
Saying no to a good, reasonable request in order to protect your own recovery is not selfish. It's the only way a limited amount of mental energy stretches far enough to cover what actually needs you.
