My greatest gain is: to accept gains and losses calmly. As the head of a family, when facing the gains and losses in life, one must accept them calmly—what is gained need not be overly celebrated, and can be shared with family, while what is lost need not be dwelled upon. It is also important to remember that family is the warmest harbor; one should not casually vent their bad emotions and worries to them. More steadiness and tolerance can support the harmony and peace of a family.
