Our success depends a lot on our worldview, taking responsibility, and leading the life.
The mindset of successful people has no place for blaming others. History shows people who succeeded in life have failed multiple times. What kept them going was that they did not give up.
Seeing opportunity in adversity makes the journey less painful. I am not saying you become delusional but living a rational optimist.
Giving up is easy. Blaming others is easy. What is difficult is owning our actions and responsibilities.
