Door Hanger quotes

[15goddess15]

Hey Guys!
Ok, really wierd question, but what two famous quotes would be suitable to put on a door hanger? A quote that suggests not to disturb one in deep thought, and another about nothing is more welcoming than a face with a smile - something like that anyway!
I just want to do something besides "do not disturb" and "come in".

Thank you! Jaqui

"We say, Mr. Jones, we're going to cut this tree, this tree and this tree. And we want you to know that, ask us questions and sign off that you do understand what we're going to do. Most utilities put a door hanger on the door and it says: beginning next Thursday, we're going to start trimming your trees." - Ed Clark
