to improve or advance to a higher level
向上するまたはより高いレベルに進む (kōjō suru matawa yori takai reberu ni susumu)
"With his hard work, he has been able to level up in his career."
"彼の努力のおかげで、彼はキャリアでレベルアップすることができました。" (Kare no doryoku no okage de, kare wa kyaria de **reberu appu** suru koto ga dekimashita.)
to gradually adjust to changes or new circumstances
to express anger or frustration so that you feel better
the most vulnerable or insecure part of a system
the complete truth without leaving anything out
to cost too much; to use up all your money
doing wrong or illegal things will never bring true success
