What is a quote in To Kill A Mockingbird that teaches the solution to hypocrisy (judge yourself before judging others)?

From the text:

"'First of all,' he said, 'If you can learn a simple trick, Scout, you'll get along a lot better with all kinds of folks. You never really understand a person until you consider things from his point of view-'

'Sir?'

'-until you climb into his skin and walk around in it."
