“you are you for a reason don't try to change”
“Don't try to change Doofus, let Doofus change you.”
“Be what you are. Don't change yourself for anything. God made you that way for a reason.”
“You're fine the way you are. Don't try to change it, try to better it.”
“Instead of agonizing about the things you can't change, why don't you try working on the things you can change”
“Once you've chosen a man, don't try to change him', I wrote with more confidence. 'It can't be done. More important-don't let him try to change you.”
