求英语达人翻译如下的一段话

这也正是我的结论,所以很感兴趣,试译如下：We have to be enthusiastic about something as we live。Maybe we are not able to make the thing our career,but there must be such a thing,which gives us the very reason for us to care about and spend time on anything or anybody else。It is behind any piece of our effort and is what the stream of our life is running about at all。Without such a thing,our life will lose its purpose and become merely some meaningless bits and pieces。
