I learned about plagiarism as part of the orientation after I entered UoPeople(University of the People). Looking back, I realized that I had never studied plagiarism. After studying this time, I found that there were cases when plagiarism was done intentionally, and cases when plagiarism was done unintentionally (without thinking that one's action was plagiarism).
In this orientation, I learned "what is plagiarism?" and "techniques to prevent plagiarism". According to The Plagiarism Tutorial from Simon Fraser University:
Plagiarism means using the words or ideas of another person as if they were your own and without giving proper credit to the sources you have used.

The following is the golden rule to follow to prevent unintentional plagiarism (Intentional plagiarism is out of the question).
You must provide a citation for any facts, ideas, or data that you took from another source. The only time you do not need to cite is when the fact or idea is "common knowledge". If you are unsure whether a fact or idea is common knowledge, cite your source!

So, what is an original work that is the exact opposite of plagiarism? I think that it is a work that is based on one's experiences, viewpoints, thoughts, and values. Furthermore, I think that it will be a higher quality original work if one can tell how one's viewpoints, thoughts, values have changed due to the words or ideas of another person.
I'm going to write reports every week. I will write original reports citing the words or ideas of another person.
