There are a few that I love and have touched my life.
When I was a teenager, ny best friend's mom used to write quotes on the bathroom mirror of their house. A few have stuck with me:
"People are like tea bags. They're not worth much till they've been through some hot water."
"Success is getting up one more time than you fell down."
Now my personal favs are:
"I'm not who you think I am. I am not who I think I am. I am who I think you think I am."
There are many more, but these are the ones that stick out in my head.
