what you prefer to choose to fill your mayonnaise jar,golf balls pebbles or sand  

today,i received an e-mail from my friend,he told me a story like this discription below:a teacher picked up a large mayonnaise jar and proceeded to fill it with golf balls.
And then asked the students,if it was full,they agreed it was!
and then he filled it with a box of pebbles ,and asked the same question again,if it was full,they agreed it was!
and then he filled it with a box of sand,and the same question again,the students agredd it was!
at last ,the teacher asked the students what conclusion they get from this experiment!
another slience,finally the teacher said:golf balls represent your family,your partner,health,friends,favourite passion.they remained ,your life would still be full even if you lost everything.
the pebbles are the other things that matter like your job ,house,and car.
the sand is everything else---small stuff!
if you put the sand into the jar first,there is no room for golfballs and pebbles.the same goes for life!
so ,friends ,tell me what you should do to deal with your life,what you prefer to choose ,golf balls ,pebbles ,or sand,and then you know what to choose ,so how to do?
