To me, plagiarism is the attempt to make a fortune or falsely try to seek fame out of someone else's hard work, creativity or innovation. It is a cowardly and selfish act of dishonesty, not only to the stakeholders of your demeaning intention, but most importantly, to yourself.
I don't really understand how people can even live with that, how can they actually go to sleep after doing something of this sort and feeling no remorse whatsoever! As far as plagiarism in writing is concerned, my heart goes out to all those who have been victims of this cowardice at least once in their lives. When someone decides to write, they use 'words' as way of expressing and sharing an experience they went through in their lives. They use these words to empower someone else about something they know and/or have knowledge of. It's a sum of their thoughts, ideas and experiences that they went through. It could be due to the best moments they ever lived, or the very painful times they had to witness and be part of. How can a person even rob someone of all that and be at peace?
Suggestion to all those who have ever done or plan on doing this in future:
"Your own life will give you enough moments to think, innovate and write on.. You don't have to disrespect yourself by undermining your own life and stealing someone else's... Trust me, even if your false intentions make you famous and earn you millions in the short-run, one day you'll look at the mirror and you'll be like... why man? I was better than that!"
Respect yourself, value your own thoughts and have patience.. Your time will come, too! A little bit of faith, that's it.
Cheers! :)
