I think that's one of canadianguy's famous sayings, which I very much like and subscribe to now btw.

But here's the latest song that says it perfectly.  The lyrics are appropos and the music and beat is very upbeat and uptempo and makes me sing out loud and happy too.

Hope you enjoy

What Do Ya Think About That - Montgomery Gentry
I heard it through the grapevine
My new neighbor don't like my big red barn
A '47 Ford, bullet holes in the door
Broke down motor in the front yard

I got half a mind to paint a plywood sign
And nail it up on a knotty pine tree
Sayin' I was here first
This is my piece of dirt
And your rambling don't rattle me

Some people care about what other people think
Worry about what they say
Let a little gossip
Coming from a loose lip ruin a perfect day
Sayin', blah, blah, blah, just a jacking their jaws
Got a let it roll off-a my back
I don't give a dern what other people think
What do ya think about that

I wear what I want to, overalls work boots
Crank my music up loud
Like to sling a little mud in my four wheel drive
Trek it on into town
Shoot a little eight ball down at the pool hall
Drink a beer with my friends
Now don't judge me and I won't judge you
Cause we all get judged in the end

Some people care about what other people think
Worry about what they say
Let a little gossip Coming from a loose lip ruin a perfect day
Sayin', blah, blah, blah, just a jacking their jaws
Got a let it roll off-a my back
I don't give a dern what other people think
What do ya think about that

yours in recovery,
Maria
