GEORGE AND BOB KNOW WHAT THEY'RE TALKIN' ABOUT

"I tell you that as long as I can conceive something better than myself I cannot be easy unless I am striving to bring it into existence or clearing the way for it."

George Bernard Shaw (1856-1950) Irish writer

About as good a description of the path to self improvement as I can imagine.

Strive to become, or make way for, what will be better.

And if you can't do either, as Bob Dylan suggested, take heed: 

"Your old road is rapidly agin', please get out of the new one if you can't lend your hand for the times they are a-changin'."
