It is not a rule, but in most cases that when a person, after he reaches his goal of success usually goes to the gate of failure. The reason is very simple. To achieve success, he must contribute his full energy and time day and night in the goal he is aiming at. By the accumulation of time and plus luck, he realized his dream.
Every person, as long as he can struggle, surely has chance to be successful in his life time. But, whether you can keep the fruit of success, it is another question.
Success can only be kept if you continue to work hard after success. If you start a lazy life and enjoy luxuriously after success, failure will follow.
We are human. We hate to work hard and prefer a comfortable life. Since we have now entered the world of success, with every beautiful things in our hands. Why not we do not enjoy tonight and tomorrow is another day.
By this theory of human heart, many people who are successful in the beginning, finally fall in the end.
Therefore, the definition of success is to continue working hard after success, neglecting which will bring you destruction of failure.
