What's the ONE song that best summarizes you life's philosophy?

[Gwenevere]

Bob Marley ~ Don't Worry, Be Happy

I edited the lyrics to the relative ones

in every life we have some trouble,
when you worry you make it double
don't worry, be happy

cos when you worry, your face will frown,
and that will bring everybody down,
so don't worry, be happy

don't worry, be happy now...

listen to what i say
in your life expect some trouble
when you worry you make it double
dont worry be happy
be happy now

don't worry, it will soon pass whatever it is,
don't worry, be happy,
i'm not worried

I'm just feeling a bit on the optimistic side of life today. Yesterday I was sick, today I'm better. Last year I injured my back, couldn't walk and had back surgery;
every day is painful, but I can walk, no worries, I'm happy!
