I feel like B is the correct answer.
In fact, both suffering and setbacks vary from person to person. It is a stepping stone for geniuses and wealth for those with tenacity, but it is the nightmare of those who are depressed and have no ambition. Because type 3 people often fall into despair because of one failure. So failure is not the mother of success for everyone.
To be more specific, A is an overview and an understanding. But it’s not a method, and it’s not understood correctly. Just imagine, all these war reporters were injured on the battlefield, but there is only one Hemingway, the same reason.
B is not a metaphysical slogan, but a method. It tells us that no matter we face difficulties or setbacks. If you only think it is the mother of success, then you will not succeed. Find ways to improve yourself.
That’s a lot to say, I hope you’ll adopt it! ! !
