Optimism opens a door in difficult or hopeless situations. No matter what the crisis, an optimist maintains the outlook that it is a sign, time for a different way of thinking, or of doing things. Sometimes the signal has to be very clear even harsh, otherwise we may continue in self-delusion and not wake up. Of course if we lack optimism, instead of taking this signal as a step towards renaissance, complaint, resentment or even desperation will emerge.
