English business writing for non-native speakers — what actually helped

Grew up speaking primarily Bahasa Malaysia and Hokkien. My written English was functional but not confident. Here's what moved the needle.

What didn't help: Generic English grammar books. They address language mechanics, not professional writing judgment.

What helped:

Reading high-quality business writing deliberately. Not just reading — studying. The Economist, McKinsey Insights, and well-written annual reports. I read one article per day and noted how ideas were structured and how sentences were built.

Writing and getting feedback. I started a personal blog (not public) and asked a colleague who wrote well to review posts occasionally. Specific feedback on real writing is worth more than any course.

Plain English principles. The UK government's writing guidelines are free and excellent. Core idea: short sentences, active voice, one idea per paragraph.

The specific skill that improved everything: Learning to write the main point first, then the evidence. Most non-native writers do the opposite — build up to the point. Reversing this transformed how my emails and reports were received.
