What is friction reduction?
Friction is the effort created by setup, missing materials, repeated decisions or awkward steps between an intention and an action. Friction reduction removes a specific obstacle. It does not require optimizing every part of your life or buying a new system.
Some friction protects privacy, money or safety. Keep useful checks and reduce only the effort that is getting in the way of your chosen action.

How to use friction reduction
1. Observe the setup barrier
Notice the first point where progress stops.
Example: You postpone scanning a form because the scanner app is hard to find.
2. Remove one unnecessary step
Prepare the materials or simplify access while retaining useful safeguards.
Example: Put the scanner shortcut next to the folder where the form belongs.
3. Try the task again
Check the whole action, not just the attractiveness of the new setup.
Example: Scan one page and confirm that it is readable and saved in the correct place.
These examples are illustrative. Adjust the steps and timings to your situation.
When to adjust the approach
Some friction protects privacy, money or safety. Keep useful checks and reduce only the effort that is getting in the way of your chosen action.
Evaluate one situation at a time. If the change adds more effort than it removes, simplify it or ask what is still making the task difficult.

- Useful defaults that you can change
- Export and search without another configuration project
