In our lives, we face a lot of opponents. They challenge us, try to defeat us and take away our dearest dreams. “Homo homini lupus est”: man is a wolf to man. If you’re an athlete, your challengers will do everything they can to spoil your goal to become a champion. If you’re an entrepreneur, your competitors will fight for your market share. If you’re not strong and smart enough to beat them, defeat is what you will always get.
