You make sure your shoes are shined.
You say 'please' and 'thank you.'
You treat those around you with respect, and when you screw up you say 'I'm sorry.'
You eat your veggies and take your medicine.
You tell your mom you love her as much as possible.
You work hard. And honestly.
You tip generously. At least fairly.
You keep your fingernails clean.
You hold the door for strangers.
You eat a healthy breakfast.
You find your cocktail, and stick with it.
You try to teach your kids how to be good by acting good.
You choose what issues in life need to be taken seriously; and those that are inconsequential.
It's all pretty simple.
