There is a difference between contentment and complacency

We just wanna be the happy bums that we are. That's all.

Contentment - being happy while doing something - and complacency - being happy while doing nothing - are entirely different.

Good humor is one of the best articles of dress one can wear in society.

One can be content and not be complacent.

Complacency may often result from being surrounded by a team of flatterers and false people around. A true member of a team would step in when he sees someone complacent.
