If a person has to prove himself through the evaluation of the outside world, it only means that his heart is not strong enough. Only when he no longer needs to rely on the judgment of the outside world and can prove himself, will his heart be truly strong. A person with a strong heart can truly be fearless. Only with a strong heart can we live calmly, unfazed by favors and disgrace. No matter how many temptations or setbacks there are in the outside world, we can remain focused and still stick to the firmness in our hearts. Women especially need to be mentally strong.
