“I know you’re sick of studying, but just soldier on through one more week of classes, and then you’ll have a vacation.”
Sometimes you have to keep going through difficult conditions or keep working at an unpleasant task. At a time like that, you must soldier on until the end.
「勉強にうんざりしているのはわかるけど、あと1週間頑張ったら休みだよ。」
つらい状況や嫌な仕事を頑張り続ける必要があるときは、最後まで soldier on （頑張り続ける）しないといけません。
