"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'."
