Success is better teacher. If you get used to the failure, you will not get used to the success. Many things in our life, we don't have chance to fail 700 times. If we fail more that few times, we may lose our job, lose our marriage, lose our lives ....Failure is a great teacher.
How many times can you fail in your SAT, GRE exam? When a knife is stabbing toward your chest, if you just fail once, you will be dead.
