It's only best to write when the feeling's height, that is when it is best. Not when your thought's are singing a popular song, you feel as if you need to write along. It comes from you, not someone else, It comes from the silent heart, not a pair of head phones. If you've plagiarized, you are not a writer, you are just another plagiarizing fool.
To the people who feel a need to rip off others work and claim it for their own. You know who you are.(;
