I have always believed that a person alone is responsible for his situation. There are no excuses for blaming anyone for his shortcomings. "Man can have nothing but what he strives for." I strongly believe this, meaning that a person alone is capable of changing his situation, creating opportunities, and creating the means to help him adapt to anything without waiting for help.
And even if all the changes aren't met and there is plenty of failure, doing what we know we should brings value in and of itself.
