The qoute is definitely correct .
As for example : you can take yourself also , as the change made in your life is the change made by you . All that success or good chances you are living today is made by your own hardwork .There is no one who can give you assurity of life full of success or joy without any ups and down .
So its the person's hardwork and selfesteem which helps him to make a change in life.
