Imagine for a minute that you saw someone create a successful business, so you decided that in order to be successful, you'd copy their business almost completely. You did everything like they did. And you became successful. You succeeded in imitating someone else's concept.
How would you feel? Probably good because of the profit and your ability to copy the other business. But there'd be another part of you that didn't feel so great, because to copy another person, you had to silence a hope in you. You had to silence the hope that said you have what it takes to do your own thing. The hope that said "you're creative enough, you're smart enough and the world needs your uniqueness." That hope had to be sacrificed for you to put your chips on imitation.
When we live imitating others, we don't just harm ourselves when we sacrifice the hope, we harm others as well. When we live like that hope isn't real for us, we are also living like it's not real for others. If you aren't living like it's true for you, then how can you tell someone else it's true for them?
Herman Meville gets it. It is far better to fail in originality than to propagate the lie that you can't succeed being original. The world doesn't need more of the same. The world needs you in all your uniqueness. Go ahead and try originality. That risk is better for everyone than if you succeeded in imitation.
