"Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else."
-- Charles Dickens, David Copperfield
People state that, "it is not meant to be," when they did not achieve what they wanted to achieve. I do not believe on this though. If you let your goal slip up, other people could benefit on it.
Would you rather sulk up at the side and watch and envy other people achieving their dreams. Work and aspire for your goals and you will not regreat when you are old, dying, and hungry.
