The impossible is often the untried.
It is human nature to consider all untried efforts as impossible but in reality it is not like that. Human personality is equipped with different competencies and traits to make impossibilities of life possible. Confidence, determination, courage, initiatives are few of them to make possible the untried efforts. Expedition of Mount Everest, K-2 was an impossible destination for many of mountaineers until it was untried but human determination and courage converted this impossible destination into a attainable one. It is a simply a matter of perception , attitude and efforts one uses to achieve something.

History is full examples, which apparently looks impossible but initiatives and efforts made them possible. Expedition of moon was an impossible; perhaps a mere dream for many people on earth but an attempt of space scientists at NASA enabled Neil Armstrong to conquer the moon convincingly. It is the matter of self believe , determination of an individual that determines the results of his endeavors. Conversely all untried issues, matters and destinations look unsolvable and unapproachable. To find a sea route to oriental counties was a once an impossible for many of European sailors however great will of Portuguese sailors made this once impossible discovery into a possible destination.

It is a human illusion to consider all untried as an impossible however it is all about the attitudes that determine the possibility of efforts.
