If you wanted to become a doctor, say, and flunked out of school, how would you find another path to become a doctor; start again in another country? Sometimes the cost of failure is high.
It is, but sometimes there is no choice but to do something else. And the cost of my own "failure" was high, though I wouldn't label it as a failure. That word is barely in my vocabulary...I prefer to consider it as a learning experience.
