As kids, we would spend the whole day at the beach, building a sandcastle, so high that it would reach the sky. One step after another. But, it could take only a wave, or just one absent-minded person to make the structure collapse. So then, you would have to rebuild it from the remaining ruins or start over the whole structure.
It can be exhausting as kids, and as grown-ups when you try to progress and the sand slips beneath your feet. But, lets start over, once again. That’s what resilience is about.
