We can't control what happens to us. We can control how we handle the situation. We can adjust our attitude.
I have a bad attitude about things sometimes. I get wrapped up in "why is this happening to me" and "this isn't fair". It's something of which I'm now very aware. So I have a choice: wallow in my maladjusted 'tude or change my perspective. I choose the latter.
Subsequently, my normally sky-high stress level has plummeted. It might just be the best feeling in the world.
