If a person want to build a good career then he or she need to prepare for it unless it can't comes into the reality. Life is always like a drama we are not the one who determines roles in this drama the producer the one who gives the role that is the god but if our wish and aim are in the correct goal then the dream will came into real life. Hardwork is the thing needed for the building of a career never a focus can bring the dream into reality it needs real hardwork. Time is equal for everyone, famous scientists like Albert Einstein, Thomas Alva Edison etc also got only 24 hours in a day so we also getting this 24 hours, the main fact is they used it carefully and usefully. Success is a story which begins with a dream and ends happily. So making a career is not easy but it will be easy if there hardwork is paying off.
