A man had a bucket of Indian crabs. The crab bucket did not have a top on it. Why were the crabs not able to escape?
If there were only one crab in the bucket it would certainly escape. However, when there is more than one crab in the bucket, if one tries to crawl out, the other crabs would grab hold and pull it back down so that it would share the same fate as the rest of them.”
This is true with people. If one person attempts to better himself, other people will attempt to drag him back down to share their fate.
You must ignore the crabs if you want to be a success in life.
