It took One test to make us feel like failures

One failed attempt at love, that made us fearful of love

One great friend to betray us, for us to believe no one can ever be trusted

One failed shot, to make us believe that we should never take risks.

But then...
  
It took One word to begin a friendship

One smile, to begin a relationship

One achievement for us to believe we are achievers

One opportunity, for us to believe anything is possible.
