Avoid people that act like a victim in a problem they created.

Never complain even if it's not your fault. Some people are not used to complain that is the best attitude. 

Never complain and never explain.

Benjamin Disraeli

A thankful person is thankful under all circumstances. A complaining soul complains even in paradise.

I'm fearless, I don't complain. Even when horrible things happen to me, I go on.
