Mine is a little faith reminder, mostly for myself, as I listen to the birds here break into a symphony each morning before the dawn breaks.
I often use quotes from Winnie the Pooh, one of my favourite inspirations. One I particularly like is “Promise me you'll always remember: You're braver than you believe, and stronger than you seem, and smarter than you think.”
I change my avatars and my signature on as whim, you can often tell how I am feeling just by watching my choices. Right now I am "one with the birds"...loving watching the migration as they pass through my little bay.
