The quotation uses a bend in the road as a metaphor for an unexpected change, difficulty or interruption. A turn may prevent someone from seeing what lies ahead, but it does not necessarily mean that progress has ended. The distinction is between encountering an obstacle and allowing that obstacle to stop further movement.

The second sentence places emphasis on adaptation. Continuing forward may require changing direction rather than insisting on the original path. In this sense, the quotation connects resilience with flexibility: persistence does not always mean doing the same thing repeatedly, but can involve recognising changed circumstances and responding to them. The image is therefore useful for describing setbacks that require adjustment rather than abandonment. Its central idea is that disruption need not become defeat when a person is able to recognise the change and make the necessary turn.
