College advice for an incoming freshman.......

I heard this from one of my friends. I think it's pretty sound advice, but I'm not sure what point the grandpa is trying to make.

My son was heading off to college last fall for his freshman year. His grandpa took him aside and bestowed some pearls of wisdom on my boy........

Grandpa: Son, when I was your age me and my buddies made it our goal to drink Budweiser out of business.

Grandson: (laughing) Seriously?????

Grandpa: Yes, it's actually true. But do you know what happened as we attempted to drink them out of business?

Grandson: (puzzled) No.

Grandpa: They opened more bars.
