Setbacks and pressure are part of the fabric of daily life. When faced with problems such as excessive career demands, serious trauma, sickness or sports injuries, people can use mental toughness or resilience to get through the bad times and prepare for the good. Leaders, and the members of their organisational teams, also need resilience to keep them going in the face of relentless stress. Developing the tools and resources to unlock mental toughness has the potential to benefit every aspect of our lives.
