Mental toughness was one of my father’s favorite topics. He believed it was the single most important skill leaders could develop in themselves and in the people around them. Mental toughness is the ability to hold onto your goals in the face of the pressure and stress of current reality. It’s the ability to hold on, and hold onto what you want in the face of what you’ve got. Mental toughness is the glue that holds a team together when the heat is on and helps that team persevere just a big longer, which in many cases is just long enough to outlast the opposition.
