Some people think that wealth is the main reason for success. Being wealthy can be one of the reasons for success, but it is not necessarily the only measurement of success. Even poor people can become successful if they are educated, clever and energetic.
Many people think that money, success and happiness are all the same thing, but they are often wrong. A wealthy person can fail at everything he tries. He can be uneducated, unloved and lonely in spite of all his money. If a poor person sets realistic goals for himself through his education, his relationships and his job, he can be successful every day of his life.
This is an example of a clear way to say what I thought you were trying to say. Please don't turn this in as your own work. It would be dishonest.
