Best-in-class sounds like a position to aspire to.
To more accurately describe best-in-class, we could call it either forever-chasing-the-leaders or struggling-to-do-the-same-thing-the-other-laggards-are-struggling-to-do.
When you’re the one defining best-in-class, then you’ll have competitive advantage. There’s no competitive advantage in copying.
Take a lesson from the leaders: if you want to be the best, be yourself. Let the others follow.
Why not try?
