Incorrect. Remember, a Wikipedia article should be neutral, balanced, and fair to all views. You want readers to have access to facts, and trust that those facts will lead them to their own conclusions. This is the policy known as Neutral Point of View.

Incorrect. You should be using reliable, published information, but you want to be very careful not to plagiarize, or closely paraphrase, those authors. Instead, you should seek out good information and summarize those facts using your own words.

Incorrect! Wikipedia is not a personal webpage or blog. You don’t want to share personal stories, even if they relate to the topic matter. Instead, find trusted, reliable sources, and cite them.
