Always leave yourself a spare key hidden somewhere in your yard so you don't have to break your window to get back inside.
Don't grab a milk bottle by the top- you might pull it off and spill the milk all over the floor.
You do not have to answer every single question someone asks you about yourself.
Hold onto your diploma after graduation so you don't have to go back looking for it under all the chairs.
Do not pour out your daily contact solution until you know for a fact that your contacts are in your eyes.
Never leave your keys, wallet, or phone unattended...there are bad people out there who will steal these things.
Bring joy wherever you go and joy will find you :)
