There are lots....

[Paul Whybrow]

There are lots of ways of being miserable, but there’s only one way of being comfortable, and that is to stop running round after happiness. If you make up your mind not to be happy there’s no reason why you shouldn’t have a fairly good time.

Edith Wharton

I had a friend tell me "I just can't stay happy." I told him, "You shouldn't be looking for happiness. You should be looking for contentedness." Trying to be happy all the time is like trying to make everyone above average.
