Optimism is the key that unlocks possibilities in challenging or seemingly hopeless situations. No matter the crisis, an optimist views it as a sign, a nudge towards new ways of thinking or acting.

Sometimes, these signs must be clear, even harsh, to shake us from self-delusion and spur us into action.

Without optimism, we risk responding with complaints, resentment, or even despair, rather than seeing the opportunity for growth and renewal.
