What does Luke 6:42 mean?

How can you say, 'Friend, let me get that speck out of your eye,' when you don't see the log in your own? Deal with your own issues first, and then you'll see clearly to help your friend. Luke 6:42 - Modern Text Bible

(Self-awareness and humility come before trying to fix others. You need to address your own problems before you can help anyone else.)
