I don't know what to write
Start from the reader's question, not your own mind. What is the one thing someone wants to understand or solve? Write down five questions people actually ask about your topic, then pick the one you can best answer. If you have no topic at all, keep a running list of things that confuse or interest you, and write about a recent one.
I can't start
Shrink the first task. Do not aim to write the piece; aim to write two sentences that state the main idea. Use a timer for ten quiet minutes. Skip the introduction and write the part you already understand. Starting small and rough is the whole trick.
My introduction is weak
Cut the general opening. Start with something specific: a fact, a moment, a short scene, or a question. Shorten the first line, state what the piece is about soon, and give the reader one clear promise. If in doubt, write the intro last, once you know what the piece actually became.
My writing sounds boring
Be concrete. Replace abstract nouns and general statements with specific details, names, numbers and examples. Use active verbs. Vary the length of your sentences. Read it aloud and mark anywhere you would skim — then cut it or make it specific.
My paragraphs are too long
Check whether a paragraph covers more than one idea; if so, split it. Aim for a topic sentence, a few supporting sentences, then a break. Five sentences is a rough ceiling for most non-fiction. Add a break (whitespace) so the reader's eye can rest.
I repeat myself
Read the piece and underline every point stated more than once. Delete the weaker repetition. Use a word-density check to spot words you overuse, and replace them with synonyms only where it improves the line. Repetition can be a rhythm tool — but only when it is deliberate.
My sentences are confusing
Find the subject and verb of each sentence. If they are far apart or buried, rewrite so the subject leads. Split long sentences in two. Cut clauses and asides. If you have to re-read a sentence, it needs simplifying.
I don't know how to end
The conclusion should state what the piece established and why it matters, without new arguments. Go back to your main point and restate it in a fresh way, then give the reader a place to land. If you still cannot end, your structure is the problem — revise the middle before the ending.
I have too many ideas
This usually means you have not chosen. Pick the single point the piece is about and write it in one sentence. Keep the other ideas in a separate note to use later, and cut anything in the draft that does not serve the chosen point. One strong idea beats five scattered ones.
I don't know how long my article should be
Match length to format and audience. A blog post is usually 800–1,500 words; a magazine feature can be 2,000–4,000; a newsletter 200–600. Check the publication's guidelines for a stated range. When in doubt, write enough to cover the point fully and no more — useful beats long.
I don't know how to research
Define the question you need to answer. Search for reliable primary and secondary sources, prefer the original, and record where each fact came from. Take notes in your own words. Verify numbers against more than one source before you commit to them. Do the research before you draft.
I don't know how to cite sources
Whenever you use a fact, idea or direct quote that is not your own or common knowledge, give credit. Quote exact words with quotation marks; paraphrase everything else in your own words and still cite. Follow the style your field or publication requires (APA, MLA, Harvard, Chicago), and keep a bibliography of everything you used.
I don't know whether my writing is good
Use criteria, not a feeling. Is it clear to a cold reader? Does it do its job? Does it hold together? Is it free of errors? Get one specific critique — what confused them — rather than reassurance. Compare it against a writer you respect. A piece is good when it does its job, not when it is flawless.
I keep making grammar mistakes
Learn the few rules that cause most errors: subject-verb agreement, comma splices, run-ons, sentence fragments, homophones (its/it's, their/there). Set your spellchecker to your English variety and turn on grammar checks. Read aloud to catch what your eye skips, and keep a personal list of the errors you repeat.
I can't finish my draft
Finishing is a separate job from perfecting. Get the whole thing down in an ugly first pass, then stop and let it cool. If you stall, write the next section you understand, even out of order. Set a small completion goal (finish the draft today, however rough) rather than a quality goal. You edit after it exists.
My writing sounds too formal
Loosen the register. Prefer everyday words to academic ones, write to a person rather than to 'the reader', and cut unnecessary formalities. Use contractions where they are natural. Keep the clarity — sound like a clear person, not a stiff document; formality is a tool you choose, not a default.
My writing sounds too casual
For a professional or academic context, tighten up. Remove slang, fillers and excessive exclamation marks. Replace contraction-heavy casual phrasing with standard forms, prefer precise vocabulary, and avoid starting sentences with 'so' or 'and'. Read it and ask: would this sit comfortably in a formal document?
I don't know what an editor wants
Read the publication's official guidelines — they say what they accept, the length, the pay, and the rules. Then read several recent pieces they published to see the style and the audience. When you pitch, show you fit that specific publication. Never guess: check the guideline, and never invent a requirement.
