Crabs in the bucket

I like this story i read from Yan's blog.

"Why don't you cover you bait so the crabs won't escape?"
"You don't understand."

"If there is a crab in the bucket it would surely crawl out very quickly."

"However, when there are many crabs in the bucket, if one tries crawl up the side, the others would grab hold of it and pull it back down so that it will share the same fate as the rest of them."

So is the real world. If we get better grades, improve ourselves, be outspoken, think ahead or dream big, others will try to drag us back down to share their faith.
