Those brilliant scenes that unfold during your morning walks (thanks, DMN!) require a different mental state to become actual words on the page. Today, we’re exploring your brain’s implementation engine: Executive Function.
Understanding Executive Function: Your Implementation Engine
Your Executive Function network transforms raw creative materials into finished work. When properly engaged, it helps you focus deeply, organize complex elements, and refine ideas into polished prose. Research indicates it works best in concentrated blocks of 40-90 minutes, followed by brief recovery periods.

This Week’s Implementation
Identify Your Peak Performance Windows
- Track your focus levels throughout the day
- Note when complex tasks feel easier
- Document your natural work rhythms
Create Implementation Zones
- Design a distraction-free workspace
- Remove DMN triggers during focus time
- Establish clear start/stop signals
Build Focus Blocks
- Start with 40-minute focused sessions
- Take 10-minute recovery breaks
- Gradually extend duration as stamina builds
Your Action Steps
- Read the “Executive Function Optimization” section in Chapter 1 here
- Implement three focused work blocks daily
- Track your results in your creative oscillation spreadsheet
This Week’s Challenge
Choose one creative project and complete three focused implementation sessions. Notice when your energy peaks and fades.
Remember: Your Executive Function and DMN are partners, not competitors. Success comes from allowing each network its own time and space to operate.
Next week, we’ll explore how to create smooth transitions between these two modes.
