## 매 핵심

### 매 components
- **Perseverance of effort**.
- **Consistency of interest** (= passion).

### 매 critique
- **Credé 2017 meta**: 매 grit ≈ conscientiousness (Big Five).
- **Limited incremental validity** beyond conscientiousness.

## 💻 패턴

### Grit Scale (12-item, Duckworth)
```python
def grit_scale(responses):
    """매 1-5 Likert."""
    perseverance_items = [responses[i] for i in [0, 2, 4, 6, 8, 10]]
    interest_items = [6 - responses[i] for i in [1, 3, 5, 7, 9, 11]]  # 매 reverse
    return {
        'perseverance': sum(perseverance_items) / 6,
        'consistency': sum(interest_items) / 6,
        'overall': sum(perseverance_items + interest_items) / 12,
    }
```

### Long-term goal tracking
```python
@dataclass
class GoalPursuit:
    goal: str
    started: date
    target: date
    obstacles_encountered: list
    setbacks_recovered: list
    
    def grit_indicator(self):
        years = (date.today() - self.started).days / 365
        return {
            'duration_years': years,
            'setback_recovery_count': len(self.setbacks_recovered),
            'still_pursuing': not self.abandoned,
        }
```

### Hard Thing Rule (Duckworth)
```python
HARD_THING_RULES = [
    "Each family member picks ONE hard thing (instrument, sport, language).",
    "You CAN quit, but only at a natural stopping point.",
    "You finish what you started.",
    "Choose your own hard thing — autonomy.",
]
```

### Goal hierarchy
```python
@dataclass
class GoalHierarchy:
    """매 ultimate goal → mid → low."""
    ultimate: str  # 매 e.g., "be a great writer"
    mid_level: list  # 매 e.g., "publish a novel", "build audience"
    low_level: list  # 매 e.g., "write 500 words today"
```

### Deliberate practice (Ericsson)
```python
def deliberate_practice_session(skill):
    return {
        'specific_goal': identify_weakness(skill),
        'full_concentration': True,
        'feedback_loop': True,
        'just_beyond_current': True,
        'duration_min': 60,
        'rest_after': True,
    }
```

### Setback resilience
```python
def setback_protocol(setback):
    return {
        'feel': 'allow the disappointment for a defined window',
        'analyze': 'what specifically went wrong',
        'reframe': 'what learning is here',
        'next_action': 'one small step to resume',
        'support': 'who can I talk to',
    }
```

### Passion fit
```python
def passion_assessment(activity):
    """매 sustained interest indicators."""
    return {
        'voluntary_time': activity.weekly_voluntary_hours,
        'feel_in_flow': activity.flow_frequency,
        'connect_to_meaning': activity.meaning_score,
        'survives_setback': activity.continued_after_setback,
    }
```

### Coach script
```python
GRIT_COACHING = """
1. What's your long-term direction (5+ years)?
2. What's the hard thing you're working on?
3. When did you last want to quit? What helped you continue?
4. What's the setback that strengthened you?
5. What are you avoiding that matters?
"""
```
