The 23-minute tax you're paying every day


The Muse Letter: Issue 5

Hi Reader,

What if the reason you're exhausted isn't the amount of work you did, but the number of times you had to 'restart' your brain today?

Welcome back to The Muse Letter, a weekly newsletter for ambitious people building intentional momentum without burning out.

This is a space to think clearly about work, ambition, and consistency without glorifying hustle culture.

This week, we're covering the hidden cost of content switching.

In this issue, we're exploring:

  • An expensive 23 minutes: what context switching looks like
  • Mode batching vs. task listing
  • Protecting your energy between switches

Let's see where this letter takes us.

The Hidden Cost of Context Switching

We've been conditioned to believe that multitasking is a badge of honor. But for the multi-hyphenate, "jumping between tabs" is actually a form of mental tax. Every time you switch from a spreadsheet to a creative brief, then back to another tab, you leave a piece of your focus behind. This isn't just 'being busy', it's a slow leak in your momentum.

Context switching can look like attending a KPI meeting, then sitting back at your desk to be greeted by what seems like a thousand emails and Slack messages, switching to content ideation and scheduling, then switching back to answer more emails that are seemingly urgent… Honestly, though, at least in marketing, the world will not end if a KPI is not met by EOD. I digress…

Regardless of your profession, or even if these tasks look different due to your daily context (maybe as a doctor, a stay-at-home mom managing human and/or fur babies, or a remote engineer), we’ve all experienced being busy the whole day just to feel like we haven’t really achieved anything by the end of it. You know that drained-but-unsatisfied feeling?

There’s a lot of productivity research around this, but the number that matters most is simple:

"It takes roughly 23 minutes and 15 seconds to fully refocus after a context switch,” according to a study from the University of California, Irvine.

That means that context switching, in itself, is a very expensive exercise in the currency of time. Context switching isn’t just a distraction or focus issue that applies only to tasks, however. It sometimes signals identity friction, too.

For multi-hyphenates, the cost isn’t switching tasks; it’s switching versions of yourself.

In the same way that you switch between tasks, multi-hyphenates often find themselves switching from certain egos e.g. the self that you are at your 9-5, your creative or ambitious self who gets distracted at work when inspiration hits and needs to jot memos down not to forget their ideas (often leading to an idea graveyard that barely gets attended to), and even the self that is a friend, partner, child, or parent. While it’s wonderful to be privileged enough to enjoy so many things, switching between these versions of yourself can be exhausting.

This is why I’ve stopped batching my tasks and started batching modes. For example:

  • Morning: Administrator Mode (emails, ops, logistics)
  • Midday: Architect Mode (analytics, strategy, writing, creation)
  • Evening: Athlete Mode (movement, recovery, thinking)

How did I get to this conclusion? Personally, as an ambitious person who tends to procrastinate things I don’t want to do, I know that I’m the most motivated in the mornings, and that’s when I need to do admin tasks (especially urgent ones). Otherwise, I will put them off if I’m faced with them after all my mental energy is spent.

Then I switch into my midday Architect Mode. The transition from admin to architect almost always happens by taking a look at analytics and data because these motivate me and give me ideas on what I can do to improve. So, that fuels the strategy, writing, and creation work that needs to get done.

I also know that I always hit an energy wall around 5 PM. So, that’s the time when I’ll either take a break, wind down, or do other tasks to refresh, like cleaning around the house (if I’m home). The movement gives me a mental refresh that means that I can return to what I was doing or switch off for the night on a still productive note.

This means that I can do the most impactful work when I have high energy and drive, as opposed to having to push through or force myself to do tasks on a list with low energy.

As I said before, momentum is lost in the gaps between tasks. Stopping and starting is the ultimate friction point. By aligning my 'modes' with my natural energy spikes, I've reduced my recovery time between tasks to almost zero.

Reducing cognitive drag from context switching was the single biggest bottleneck in my career. It's the reason I'm codifying these systems into the 'Intentional Momentum Framework'. I want to help you stop pushing through low energy and start riding the wave of high impact.

I'm currently mapping out the 'Intentional Momentum Framework,' which I use to balance being a multi-hyphenate without hitting a wall. Stay tuned to this newsletter for its release.
