That hard work is a key to success is a well-known adage. Parents, teachers as
well as others guide a child to work hard so that he can achieve good scores.
Though a little bit of luck plays a positive role but I believe that hard work is
the key to success. In fact if only luck is to be considered, no one would work
but just wait till their luck shines up.
But this is not the case. Today we see that technology has improved to such an
extent that a person can have a lunch in Paris and a dinner in New York on the
same day. There lies great contributions from people like the Wright brothers
and Henry Ford to invent these means of transportation, which were the result
of their hard-work and great efforts. If these people had waited for the D-day
probably we could still have been using fire and wood to cook instead of using
electrical ovens, and the globalization would not have taken effect.
A person can excel in his career due to hard work. If he sits at home, no one
would offer him a job unless he initiates the job searching process. Also if you
are working in a company you will be promoted only because of working hard;
luck does not lie in the picture.
A student stands out first only if he studies hard. Many students after the
graduation say that probably they were not lucky enough to get good marks, or
the evaluators must have marked their papers strictly. But again these are
merely reasons that can't be given preference.
Today science has developed so much that hand shaking can be virtually done
between any two countries. This is due to the tremendous amount of researches
accomplished by scientists. All achievements in science and technology are
because of hard work contributed by people in different fields.
Thus a young individual has the potential to do something and crave in
reaching a particular acme. Whether your luck prevails or not condition being
hard work and efforts, which will pick you up wherever you are.
