If there is one thing humans do well, we excel at imitation. We apes ape.
Why do you think every high school kid dresses the same way?
Or why every MBA sounds alike using the same buzzwords?
We even copy business models.
Groupon has inspired scores and scores of copycats. And if Google is any indication, Groupon being the first mover might not win. But neither will all those me-too group buying companies except for one or two.
There are good evolutionary reasons why we imitate so well. But let's be realistic here. You're not going to create the next Groupon. You can't create the next Google. Nor will you build the next Facebook. There is no "next (insert name of existing big successful company here)."
The key to thriving and not just surviving is to come up with something entirely new. Something the rest of us haven't imagined. So we can imitate you.
