自娱自乐自暴自弃自给自足
[zì yú zì lè zì bào zì qì zì jĭ zì zú]
It translates to 'Entertaining oneself, indulging in one's own pleasures, abandoning oneself, and being self-sufficient.' Reflects an introverted attitude where one relies solely on themselves for amusement and satisfaction without needing anyone else.
