Plagiarism: copy/paste considered harmful to the source. Learn by copying effectively.

Copying may be a natural act, inherent or induced. Copying starts to become reprehensible if it would seem to giving an unfair advantage to an undeserving someone. If you are aware that you are copying someone’s work and you’re not giving appropriate credits, then you’re doing it wrong. If you’re learning from someone and using that learning to come up with something original, you are doing it right.
