It goes without saying that in our lives things will happen and people will say or do things that we don't like or will frustrate us beyond belief. I would say that it's inevitable. But it's what we choose to do with those negative feelings that will make or break us.
I had such a day, and instead of slamming my head against a desk, or throwing a toddler-like tantrum, I took a page out of Wreck This Journal and filled it with circles instead.
I'm well known for needing a mental time-out sometimes, and today my journal saved me. All it took was a good 10 minutes or so and all of the wrongs of my day have been righted with the colourful repetition of circles.
