Foremost thing I'd like to say is
Plagiarism is NOT OKAY!
Actually it's the acceptance of defeat in the most shameful manner!
You'd say why defeat?
Well the person is accepting that he would never be able to create an artpiece or a work better than others.
Or perhaps would never be able to create anything of their own.
I'd like to say that person a few things-
You're unique. You've your own style, own aura. You don't need to undermine your talent under the impression someone being far greater than you. Why compare? After all it's an art...if you can't respect others' art then how can you expect to gain respect for yours?
Maybe what you create won't be as great as what you plagiarized BUT it'll be yours...totally yours! If you still are unable to accept this truth, do ONE thing on your own which you usually don't do. Eg- cook something and taste it. Maybe it's taste won't be more delicious than what you've eaten before but it'll have it's OWN taste, YOUR taste! If it doesn't turn out to edible😂😂 then at least you'll learn to RESPECT your mother's efforts!
