How to write papers efficiently when English isn't my first language?
The art of academic writing is essentially the practice of re-writing the same story many times, until the result is "good enough". It takes a lot of persistence and a lot of time to prepare a single paper for publication.

If English is not your first language and  you struggle with the correct phrasing, consider using an academic phrasebank  to help you. I can also recommend a brief summary of academic grammar. Finally, use English-English dictionaries as much as possible, e.g. the free dictionary, and refrain from using English-YourMotherTongue dictionaries if you can.
