Willpower is decisive. The right attitude makes you a winner. “Die innere Kraft” (The Inner Strength) by Michael Strauch is the new SPARTANAT Black Book. It aims to inspire you to explore your warrior mindset.

Keep going when others give up. Persevere when others can't go on. The right attitude: “Embrace the suck” – push through and enjoy the special challenges.

“Die innere Kraft” explains how you can train your attitude and develop your “warrior mindset.”

  • Your operating system: What soldiers should think about fundamentally.
  • The right mindset: Self-confidence and self-efficacy.
  • Warrior mindset in action: Embrace the suck.
  • The key to leadership: Lead by example.
  • A warrior's thoughts on death: Memento mori and Amor fati.

Michael Strauch combines operational experience with coaching expertise. He explains how you can nurture your inner strength and live the warrior's path as a soldier. Without pathos, with knowledge and attitude. Right up to the very end. Because it is always your attitude that makes you a professional. And your will that makes all goals achievable.

“THE INNER STRENGTH” by Michael Strauch, SPARTANAT Black Book 17, pocket-sized paperback, 140 pages, $15.90 – available directly from us in the SPARTANAT Shop.
