  fish); ask questions that lead them to insights

✓ Be PATIENT and supportive → they're learning; create a safe space to ask and make mistakes
✓ Give constructive FEEDBACK → specific, kind, growth-oriented; review their work helpfully
✓ Encourage and build CONFIDENCE → recognize progress; help with imposter syndrome
```

## Effective mentoring practices

```text
✓ Meet them where they ARE → tailor to their level, needs, and goals

  being stuck too long (balance support and independence)

✓ Be available and approachable → make it easy to ask questions
