## Meaning

"Don't boil the ocean" means don't try to do something far too big or solve everything at once; focus on a smaller, realistic scope.

Boiling an ocean is impossible, so this idiom warns against huge, unrealistic plans: "Let's not boil the ocean. Start with the top three customers." It is common in consulting, product and engineering planning. It is almost always negative and usually appears as "don't" or "let's not".

## When you hear it

You propose rewriting the whole system, and your manager says: "Let's not boil the ocean."

## Examples

- **in a planning meeting:** "Let's not boil the ocean; we'll support two payment methods first."
- **in a design review:** "Migrating every service at once would be boiling the ocean."
- **in feedback:** "Your plan is good, but it boils the ocean. What's the smallest version?"

## What native speakers say

- "Let's not boil the ocean here."
- "We don't need to boil the ocean for the MVP."
- "Trying to fix every report is boiling the ocean."

## Common mistakes

- ✗ "Let's boil the ocean! (as encouragement)" → ✓ "Let's think big." (Boil the ocean is negative. For ambition, use other words.)
- ✗ "Don't boil the sea." → ✓ "Don't boil the ocean." (The idiom is fixed: ocean.)
- ✗ "We boiled the ocean yesterday. (meaning we worked hard)" → ✓ "We worked really hard yesterday." (It describes an unrealistic scope, not hard work.)

## Be careful

Use it to push for a smaller scope, kindly. Telling someone their idea boils the ocean can feel dismissive without an alternative.
