When Should You Use the Word Diligently?

- Talking about something done carelessly.
- The effort or consistency isn’t important to the meaning.

This sounds unnatural because sneezing isn’t a deliberate task.

People choose diligently because it expresses more than just hard work.
It suggests someone is:
- Reliable
- Disciplined
- Careful
- Persistent
