ONLY I CAN CHANGE MY LIFE.
NO ONE ELSE CAN DO IT FOR ME.

This is true.
The fact of life is no one cares much about you. It is only us who can change our life, our future. Everyone wants to be at the top, successful. We have to fight for our position. No one else will. Some may initially, but at the end, it is us who have to take our stand.
Be confident and do your best to change your life. Don't depend on anyone else except you.
