"All iz Well" - is all well with us?

Aamir Khan gave his batchmates a "tasalli" that "All iz Well" - which he had heard at night from the shout of a watchman as a small boy - which he believed in and told himself whenever he was scared while facing an unknown situation. In reality, everyone knows that "All is not Well", but the watchman's word were etched in the mind of Aamir Khan and helped him to overcome his fear of unknown. How many of us share his method of overcoming the fear of unknown? Is it not uncommon to see such beliefs all around in ourselves and other people? Do you also have such beliefs? Do you know if someone has such beliefs which helps them to go through tough situations in life? Do you want to share? Have we not gone through our own childhood when someone has ridiculed us for believing in something ? Is it just a belief system or does it really work? What do you think?
