Looking for a theme verse

I am looking for a theme verse to hold onto for 2006-something simple to keep in the front of my mind, to remind me to keep things simple. So far, I'm considering the following...

The boundary lines have fallen for me in pleasant places;
surely I have a delightful inheritance.
Psalm 16:6

A cheerful look brings joy to the heart,
and good news gives health to the bones.
Proverbs 15:30

"Lord, to whom shall we go? You have the words of eternal life. We believe and know that you are the Holy One of God."
John 6:68-69

The LORD is my light and my salvation—whom shall I fear?
The LORD is the stronghold of my life—of whom shall I be afraid?
Psalm 27:1

They seem sort of random here listed out, but they make some sort of organic sense to me. I need to meditate on it.

I am open to feedback and suggestions.
