If you aren’t fighting for something bigger than yourself, you’ll be nothing more than just one more ambitious, opportunistic asshole who’s trying to claw his way to the top. Personal ambition may motivate you, but it’s not going to motivate anyone to follow you. Being a warrior and a leader is not about achieving personal success. Success usually does come to leaders, but to a real leader, personal success is just a secondary gain – a nice payoff, but not the real prize. The real prize is achieving the victory of a great principle, like freedom, or peace, or the prosperity of the many.
Therefore, a real leader is actually a servant. He’s the servant of a great cause.
