Content and complacent

Today we did a meaningful job of learning and doing recycling, its just like old times doing CIP, feel good about giving back to the environment and society.

The experience brought back many thoughts about life.

People tells us to be contented with life.

Your manager tells you not to be complacent.

So we'r supposed to be two different kind of person in life and in work?

I really don't know. 

Should I be or not be contented with my house?
