0 to do or finish an unpleasant but necessary piece of work or duty so that you do not have to worry about it in the future -- 熬過,做完,結束(不樂意但必須做的事)
We can complete it step by step however long the road is and it can't be completed however short the road is if you don't even mark your footprint.
再长的路,一步步也能走完,再短的路,不迈开双脚也无法到达。
