英文小作文：

Hardenness is a common phenomenon in our lives, whether it be in our attitudes towards failure, our resolve to succeed, or our determination to pursue our goals. However, it can be a double-edged sword, as it can encourage us to push through difficult times but also lead us to become insensitive and unfeeling towards others.

On the one hand, hardening ourselves against setbacks and challenges can help us persevere and achieve our goals, but on the other hand, it can also make us lose empathy and compassion for others, which can lead to conflicts and misunderstandings. Therefore, it is important to strike a balance between being tough and being kind, as both are essential for success and happiness in life.
