For a student, if he gets the first position in his class he will need to work harder to continue his top position in the class because the top position is a temporary achievement. If he doesn't have consistency in hard work he will lose top position. Sometimes, it creates tension also for losing top position.
This modern age is the age of tough competition where opportunities are less and competitors are innumerable. Therefore, a struggler requires sincere dedication and consistency to keep his position intact.
As far as happiness and grief are concerned I partially agree with the author. I think we should share our happiness and grief with our well-wishers only- who care about us, understand us and want us to see happy. Some people might feel jealousy about our happiness. They or their ilk may feel happiness at our grief or some of them might laugh at our grief. We should be reserved in this regard.
Believe in the existence of God the super power.
The topic of the thread is " Constant efforts required even after a success", it's not about sharing knowledge and happiness.
