Whose fault is it?

Our life did not turn out how we wanted it to be. Whose fault is it? Is the reason our upbringing or our childhood trauma or our fate or XYZ person or the country we live in?

The sole reason for how our life turns out is because of the choices we make in life, the decisions we make in life. Nobody is responsible for our present success or failure than we ourselves. Unless we take responsibility for the outcome of our life we cannot be successful.
