The next time you experience a failure, think about why you failed instead of who was at fault. Try to look at it objectively so that you can do better next time. Ask yourself: What lessons have I learned? How can I turn the failure into success? Where did I succeed as well as fail?
People who blame others for their failures never overcome them. They simply move from problem to problem. To reach your potential, you must continually improve yourself, and you can't do that if you don't take responsibility for your actions and learn from your mistakes.
