There are two ways to feel better about yourself. 

One is to work hard, think positively, and build a life with which you are happy. 

The second is to cut other people down with your words.  Gossip, see the bad in people, be negative and try to undercut the accomplishments of others. 

The second one is far easier.

I once read that a crab fisherman on the East coast does not need to put a lid on their catch.  Crabs will try to climb over each other continually, and all they accomplish is pulling one another down.  Freedom is never far away, but they never achieve it because they do not work together. 

Don’t be a crab in a bucket.
