I want to help my wife find confidence

Me and my wife got together in high school in 2010 engaged in 2013 and married in 2015, she’s always been my world and always there for me. She lacks with self confidence and I want her to see how I see her, beautiful with a huge heart, smart and funny with the perfect amount of sarcasm. Hard working and absolutely perfect in my eyes but she doesn’t see that. Can anyone give me advice to help her build confidence?
