用平常心對待 的英文怎麼說?

[1] with a calm demeanor/mind/attitude[2] like normal; normally[3] treat something like any other..[4] Do your best.[5] be relaxed and calm as if you were practicing

有人問「保持平常心」或「用平常心看待」的英文怎麼說？英文中沒有相對應的字，所以就白話翻譯即可，如以上例句。

這些例句都非常自然，如:

treat this championship game like any other game = 保持平常心打這場比賽，就像打一般例行賽

be relaxed as if you were practicing = 保持平常心，就像平常練習一樣
