(PRLEAP.COM) Management expert, James Whitley, has published a new eBook entitled Duty, Honor, & Glory - Leadership Secrets of King Leonidas. James captures the essence of the movie 300, by director Zack Snyder, and shows readers how to develop their personal leadership skills and boost career success.

Duty, Honor, & Glory is a rapid-paced guidebook to the skills required for great leadership - everything from creating a compelling vision to performing an unbiased personal self-assessment. James explains what leadership is, what it is not, and how to become an effective leader. The stories, inspirational movie quotes, exercises, and tips are designed to provoke life-changing action.

"Surveys show that 50% of all managers are ineffectual and 25% of all employees would fire their supervisor if they could," says James Whitley. "We are in the midst of a national leadership crisis. I wrote Duty, Honor, and Glory for the millions of disenfranchised Americans who want to improve their workplace skills, and find personal success."
