In any human venture, no matter how apparently small or grand, there will be setbacks and unexpected challenges to continued progress. In an ideal world, there would be no need to develop resilience, as everything would simply run smoothly with no conflicts or dilemmas. In the real world, however, the most effective organisations are those who collectively step into uncertainty, which inevitably means there will be setbacks and unexpected challenges. The Develop Resilience Human Stack helps people to engage with uncertainty and challenges by giving them confidence in their capacity for learning and growth. The Develop Resilience Human Stack is constructed by using these Human Sources.
