life

life is not easy as we think about. many things not easily achieve but with effort and struggle in that things,we might achieve it. sometimes no matter we do, we still cannot get it. but we must remember that there is a quote that "failure is the key of success". when we fail,we must plan thoroughly to not repeat the failure and if we keep maintain success,sometimes we cannot feel the sweetness of effort toward success. success can be in many terms such as: success in examination, in life,in friendship or either in our emotional. no matter what we are doing,keep smiling because when we smile,there is an aura that make we feel happy and can enjoy the life:)
