I've really enjoyed reading these quotes. I don't have a personal motto, but take inspiration from different quotes from time to time. The ones that are resonating with me at the moment are:

Life is full of endless possibilities; and
Don't let other people define who you are.

"Just as you want men to do to you, do the same way to them."--Jesus Christ (in Luke 6:31).

"Commit your way to Jehovah: rely on him and he will act in your behalf".--Psalms 37:5.
