No, in my opinion academic excellence not necessarily guarantees a successful life. This is because without an academic excellence we can still succeed in life. Success is not just about being successful in our career, we must able to enjoy and happy in all aspects of life. As a human, we needs happiness in this life, so we must do something that can we happy and having fun like shopping, traveling, picnic, camping, and so on.
Then we can still succeed in life with the talents bestowed by the God. Everyone has a special talent or ability. Some people are especially good artists and others are especially good singers. For example a good singers who have been successful without excellence academic is Dato' Siti Nurhaliza Binti Tarudin. She is a talented singer and become most popular in this country. Everyone knows her and she has many fans in Malaysia, Indonesia also Brunie Darulsalam. Until now she still popular even she already married.
Furthermore, we can also succeed on our own efforts as long as we do not easily give up. Success is bound to be successful if we work hard. As an example, when we have an own business we must learn the meaning of trouble before getting a double success. For example, all this we can see from late Datuk Sosilawati Lawiya. Before she build the empire of her own cosmetics company thus becoming a millionaire, her life is very poor. But on her effort sacrifice and daring to help the family she finally manage to become a cosmetics millionaire although at first she is only cosmetic sales alone.
In conclusion, what that I can say is academic excellence is not necessarily guarantees a successful life. There are many ways to be a successful whether on what that we doing in life, or with the talents bestowed by the God and also succeed on our own efforts as long as we do not easily give up. All this is depends on what we define successful.
