Endeavor is not guaranteed to be successful if it is not made in an effective way. For example, I studied quite hard to prepare for significant examinations. Nevertheless, I none the less did not pass these significant examinations, because my endeavor was made in a wrong way. In a word, not passing these significant examinations was my fault, and it was not because I had hard luck. When our experiencing failure, the most important thing is to have reflection on ourselves, and it is of no use blaming it for something we cannot control.
Bewaring of my fault, I have revised my strategy for preparing for these significant examinations. I greatly hope that in the next significant examination, I could make my lagging indicator be scaled down to only one digit before the decimal point and pass it^_^
