Summary of "How to stop thinking about the things that stress you out - a strategy for defeating rumination"

Brief summary

Rumination is when your mind gets stuck replaying a distressing thought (sadness, anger, fear) and it dominates your attention and mood. You cannot directly force your mind to stop thinking about something, but you can redirect it because of limited cognitive capacity—your brain can focus on only a small amount of information at once.

The recommended approach is to deliberately distract yourself by putting attention onto an activity that meets three variables: high stimulation, low stress, and moderate novelty.

Key strategy (step-by-step)

Notice you are ruminating.
Choose an alternative activity that:
- Is highly stimulating to you personally (captures most of your attention).
- Is low stress (no performance pressure, no outcome expectations).
- Offers moderate novelty (different enough to require attention but not so new it becomes stressful).
Engage in that activity until your cognitive capacity is occupied and the rumination fades.

Guidelines, tips, and examples

High stimulation

Pick activities that naturally pull you into a flow state—things you find genuinely engaging or fascinating.
Avoid low-stimulation distractors (they leave mental space for the worry to return).

Low stress

Remove performance targets (don’t set rigid goals like “must read X pages” or “must win”).
Avoid turning hobbies into side-hustles or anything that adds financial/performance pressure—if a hobby becomes stressful, find another low-stress outlet.

Moderate novelty

Choose variations on what you already enjoy rather than something totally foreign or identical to your usual routine.
Examples:
- Read a new genre instead of the same books.
- Switch from competitive games to cooperative games.
- Try mobility work instead of only weight training.
- Take a similar-but-new hobby class.

Practical reminders

Learning new skills (e.g., via Skillshare courses) can provide highly stimulating, structured, low-stress ways to distract yourself.
If novelty is too high, it can increase stress; if novelty is too low, stimulation will drop—aim for the middle.
The brain is like a TV with limited channels—filling those channels with one absorbing activity reduces space for rumination.

Quick exercise

Try listing or being aware of every object in the room. After a while you’ll notice you can’t hold many items in conscious awareness—this illustrates limited cognitive capacity.

Takeaway: The most reliable way to stop rumination is not to force suppression but to intentionally redirect attention into activities that are high in stimulation, low in stress, and moderately novel.
