I believe everybody will taste the bittersweet flavour of failure, sooner or later, just like death. Everybody will have the most torturous moments in their life, be it a loss of a beloved someone or a deathly sickness.
Those who are able to overcome these difficulties, will be stronger. But those who give up upon myriad of mishaps and trials, they will flounder and die.
Nothing can help them, except themselves.
Believe in yourself, and depend on no other but your own self.
