A story about life

A philosophy professor stood before his class and had some items in front of 
him. When the class began, wordlessly, he picked up a large empty 
mayonnaise jar and proceeded to fill it with rocks about 2" in diameter. 

He then asked the students if the jar was full? They agreed that it 
was.  So, the professor then picked up a box of pebbles and poured them into the jar. 
He shook the jar lightly.  The pebbles, of course, rolled into the open areas between the rocks. 
He then asked the students again if the jar was full. 
They agreed it was. The students laughed. The professor picked up a 
box of sand and poured it into the jar. Of course, the sand filled up everything 
else. "Now," said the professor, "I want you to recognize that this is 
your life. 

The rocks are the important things - your family, your partner, your 
health, your children - things that if everything else was lost and only they 
remained, your life would still be full. 
The pebbles are the other things that matter like your job, your house, 
your car. The sand is everything else. The small stuff. "If you put the sand into 
the jar first, there is no room for the pebbles or the rocks. The same 
goes for your life. If you spend all your time and energy on the small 
stuff, you will never have room for the things that are important to you. 

Pay attention to the things that are critical to your happiness. Play 
with your children. Take time to get medical checkups. Take your partner out 
dancing. There will always be time to go to work, clean the house, give a 
dinner party and fix the disposal." "Take care of the rocks first - the 
things that really matter.  Set your priorities. The rest is just sand." But then... 

A student then took the jar which the other students and the professor agreed was 
full, and proceeded to pour in a can of beer. Of course the beer filled the remaining 
spaces within the jar making the jar truly full. 
Which proves: - that no matter how full your life is, there is always room for a beer


Now I (Shawn) have a couple of questions after reading this exerpt:

First Question:  What is fishing in your life?  Is it the beer, the sand, the pebbles, or the rocks?  The neat thing about the beer would be that you COULD feasibly put it in first, then the rocks, etc.  Which leaves me to figure out, in my life, whether fishing is the rocks, or the beer, because I know it's not the pebbles or the sand!  What is fishing to you?

Second Question:  What in the HELL is a student doing with a BEER in class and where is that school and why didn't I go THERE?
