As a copier, you cement your position of always following the crowd and competitors.

You forgo understanding how the product you’re copying actually works; the reasons behind it’s design; the problems it addresses; why it performs the way it does.

You blindly put your faith in the person or product you’re copying and, thus, give up your ability to develop and monitor expectations.
