Boundary Definition
The ability to distinguish preferences from non-negotiables and be clear about what you will and won't accept.
Understanding the skill
Why this matters
- Unclear boundaries get violated because others don't know them.
- Clear boundaries prevent small violations that become big patterns.
- You know what you're willing to accept before being tested.
What goes wrong
- Being unclear about boundaries and expecting others to guess.
- Treating preferences like non-negotiables.
- Setting impossible boundaries that you can't enforce.
Best practices
- Distinguish between 'I prefer' and 'I require'.
- Make boundaries clear and simple, not complicated explanations.
- Only set boundaries you're actually willing to enforce.
