Indifference to fame and fortune is a noble virtue. You need this spirit when you are young, and you need it when you are old. It takes great wisdom and courage to get rid of the shackles of fame and fortune and pursue truth and science, and it takes a lifetime and all your energy. A mediocre person trapped in the quagmire of selfish distractions will never have dedication and can never achieve "wealth". Don't forget, loneliness is a kind of savings, silence is a kind of strength, calmness is the soil that breeds countless mature fruits, and it is a good medicine to cure superficial thoughts and impetuous spirit. Quiet without seeking, there is ambition. Great goals produce perseverance. Noble character comes from noble morality. Only when you are indifferent will you regard thrift, self-improvement, perseverance and dedication as happiness. Only indifferent, do not drift with the tide because of the changing situation, and do not give up on yourself because of the cold world. Only when you are indifferent will you always keep a clear head, be modest and prudent, guard against arrogance and rashness, and not be tired of playing with things. Only if you are indifferent, your thriving talent will be more vigorous, and your wisdom of exerting the waste heat in the corner will be more vigorous. Indifferent and quiet, self-improvement.
