Trying to walk the walk and not just talk it

Been a Christian for years but honestly my kids probably learn more from watching how I treat people than anything I say about faith. Had a moment this week where I was really impatient with a cashier who was slow and my daughter called me out on it later. Said something like "Didn't you say we should be kind?" Humbled me big time. I'm realizing I need to work on actually living out what I preach before I can expect my kids to take it seriously. Anyone else working on being better about this?
