What I think of plagiarism

We NEED to cite our sources because if we don't then that's plagiarism and you can't steal someone elses work and claim it as your own. You have to give them credit for the work they have done. I couldn't imagine doing this. When writing a paper I have not once thought of stealing someone elses work and claiming it as something I thought. I want to be able to feel proud of my work and feel that sense of accomplishment when turning it in and getting the grade i deserve. I would be very upset and mad if someone were to use something that i put full effort in and them use it as something they came up with. It's just something you don't do in school as well as professionals in your career.
