Cut the alpha-male bravado bullshit.
It might fool a few vulnerable and immature women.
But the vast majority will wonder: "Why is this guy so petrified of being himself?"
And if that's not incentive enough to be authentic, consider this: Freddie Mercury played to crowds of 80,000, while a pitch-perfect Queen cover-singer only plays to pubs.
Authentic you is infinitely more valuable than anyone you impersonate.
