This is my favorite artist, Sunaliza. She is also my daughter. You can listen to her songs on soundcloud.com:
http://soundcloud.com/sunaliza She is a completely self-taught musician and singer and these are her own pieces. I like how she is not trying to be like any of the singers with "big" voices, just nice and simple, letting her own "voice" come through and telling her own story. I strive for this in my own writing, and I push for this while editing.
Use short sentences and every day language. The goal is to transmit information, not impress anyone with your ability to use a thesaurus.
Priorities in writing:
1. Grammar.
The most common problems I correct are tense (use in the Simple Past tense for all but about 98% of the cases), and translating directly from Turkish and not bothering to rewrite it so it is functional English. This is a sign of poor planning (not leaving enough time to translate properly) or of thinking no one will notice below average performance...in other words, it means you don't mind being judged as unprofessional.
Have your friends read your drafts and make suggestions!
2. Vocabulary
The biggest problem is people trying to use the biggest words they possibly can-- and not understanding what they mean. Sometimes they know what it means, but the grammar is so weak that the contrast looks silly. It's as if you left the house dressed in wedding clothes on top and pajamas on the bottom.
Use every day words. When I edit your text, I will "upgrade" wherever I think the word you have chosen is too informal or not concise enough.
If you are having trouble writing, try imagining someone you love who is intelligent who knows nothing of your topic but is curious, and explain your topic to him or her. Or you can use your cat. Or a stuffed animal. Or me. The important thing is to capture the feel of the narrative. Or as someone once said to me, "Just tell the story, damn it!"
P.S. Daughter is 20 and studying economics in the US.
