1. back up your words with appropriate action
you can talk the talk, but can you walk the walk?
The expression 'talk the talk, walk the walk' is used to express that someone's actions, words and behaviours should be aligned with what they say. If someone is accused of being able to 'talk the talk but not walk the walk', it means they are good at saying the right things but not behaving in the way they themselves suggest. This expression is similar in meaning to 'lead by example', or 'put your money where your mouth is'.
