고집
안되고 완벽만을 위한 것이며 목표에 영향이 없다면 효율적으로 끝가지 고집하며 스트레스 받지말고 절제하여 그냥 넘어가야 한다
뭐든 순수함이란 없다
Persistence and obstinance may seem similar, but they're different kinds of behavior.
Obstinate people are often disproportionately likely to be attached to the wrong details. Persistence often requires one to change their mind.
