All the successful people in the area are people who made sacrifices. I am not talking about rich people, wealth is never a success. Wealth can only be a result.
True, the definition of success is subjective. One can be tagged as successful because of wealth, another one could be his job title or one with a simple life.
Those who are happy and contented and those who reached their goals are mainly the successful one thus, the only person who could define his success is his own self.
