Lack of success in one’s life suggests that the person was not dedicated enough in dream. I don’t agree with this statement that failure is the result of lack of desire in a person to perform it.
First, a large number of people are unable to succeed in work they are doing because of their wrong approach to the problem. When a person does not have a right guidance or correct direction to approach the problem, it leads to failure in their attempt due to their wrong approach to it. For example, my father back in his start of his career, he tried to start his own business but every time he tried to do something new, he failed in light of the fact that of his poor choices and lack of proper guideline until my grandfather helped him to success.
In addition to this, luck also has a number of role in success and failure of a person. Thousands of people attempt to the same task however, very small number of people get to achieve it due to the fact they simply were lucky enough. For an instance, thousands of top students from all around the world apply for top universities like Oxford, MIT, Cambridge and so on but ultimately only a number of them get into those universities.
In conclusion, I believe that failing in a task doesn’t mean that they the lack desire to do so instead it means that they need to attempt it from different method and try again.
