・carry through to the end
・carry out to the end

carry through to the end/carry out to the end 可以表達"堅持到最後"。
through to the end(到最後)carry(攜帶)。

I tend to quit once I've made up my mind halfway through, so this time I want to make it carry through to the end.
『傾向於在半途而廢後放棄，所以這次我想堅持到最後』

The most important thing is to make it carry out to the end.
『最重要的是要堅持到底。』
