I think that's an over-simplification. Call me naive, but I think that to most people, "do whatever it takes to succeed" assumes a certain baseline of ethics in the intended audience.

This phrase here is meant to spur the reader to do the right sorts of "anything": being disciplined, getting out of their comfort zone, learning, taking risks, getting their "hands dirty" in good honest work, hacking and building.

The author cannot be blamed for those who act immorally because they lack ethical training or discipline.
