Explanation:

Why is it that failure may become an obstacle in someone's life?

Success is usually preceded by failure. If you take a hard look at the most successful people in history, you will see that they all failed spectacularly. Many of these individuals were regarded as enormous life failures. However, they all succeeded in reversing the situation. Failure should be defined as an opportunity for learning, not as failure.
