Help me optimize a form for completion.
FORM PURPOSE: [[FORM]] (signup, checkout, contact, survey…)
CURRENT FIELDS: [[FIELDS]]
WHERE PEOPLE DROP OFF (if known): [[DROPOFF]]
Deliver:
1. Which fields to cut, combine, or defer (every field has a cost)
2. Field order and grouping for momentum
3. Labels, placeholders, and helpful microcopy
4. Inline validation and error-message approach
5. Mobile and accessibility considerations
6. The single change most likely to lift completion
Reduce effort and anxiety, not just field count.
