some i have used in the past...
Be yourself, because those who mind don't matter, and those who matter don't mind.
Live, Laugh, Love.
No regrets, just lessons learned.
Sometimes all you need is a second chance, because time wasn't ready for the first one.
Dream as if you'll live forever, live as if you'll die tomorrow.
Live the life you love, and love the life you live.
You can never be old and wise if you were never young and crazy.
Live for the moments you cant put into words.
Everything happens for a reason.
and my personal favorite...
Whoever said that anything is possible obviously never tried slamming a revolving door.
