To be able to calmly accept the differences between people

Some people are born with strong willpower, self-disciplined from a young age, and know how to restrain themselves;

Some people are born carefree and lazy, seeking comfort and indulging their desires.

This in itself is the root cause of the lifelong gap between people, stemming from the very foundation.

Once you understand this, you won't engage in internal conflict, comparison, or blame fate and others.
