The journey of my life is an autobiography. I think that the life is a combination of two words -Up and Down,that means-
(1)Up-Success
(2)Down-Obstacles
The author is introducing his own life changes and up and downs.
The life is not so easy without we work hard .
The only thing that can change our life is only study, hard study.
Study is an only source that can change anyone's life. We can also say that:-
Study is an only weapon that can want's tochange the whole world.
