请阅读下面内容，并按照要求用英语写一篇150词左右的文章。
P= professor; S=students (In a philosophy class)
P: We all have this one life to live. A fleeting shadow amongst all that exists in this vast universe. We have the ability to accomplish anything, truly anything, if we use our time wisely.
P: (putting some golf balls into the jar) Is this jar full?
S: Yes.
P: (after add some pebbles into the jar) Is it full now?
S: Yes.
P: (after inserting some sand into the jar) How about now, is the jar full now?
S: Yes.
P: Good… (pouring some beer into the jar)
S: … (laughing, smiling, thinking, …)
P: Now I want you to recognize that this jar represents your life. The golf balls are the important things, your family, your friends, your health and your passions. The pebbles are the other important things, your car, your job, your home. The sand is everything else, the small stuff.
P: Now if you put the sand in the jar first you won’t have room for the pebbles or the golf balls. The same is true in life. If you spend all your energy and your time on the small stuff, you won’t have time for all the really important things that matter to you.
P: Pay attention to the things that are critical to your happiness. Take care of the golf balls first. The really important things. Set your priorities. Because everything else is just sand.
S: Professor, what does the beer represent?
P: I’m glad you asked. It goes to show that no matter how full your life may seem to be, there is always room for a couple of beers with a friend.
