You have posted some examples of not imitating others in their success, but there are also a lot of good examples where imitation can do good for others, like a son imitating the success of his father, that is why we have a family of doctors, a family of lawyers, imitation to some extent are good but it should be the kind of imitation that inspire you to be better, we all have real life heroes we look up and we tend to imitate so we can attain our own success.
This world is full of imitation, but imitation should originate from making yourself better and not from greed and envy.
