Some of your hurts you have cured,
And the sharpest you've survived,
But what torments of grief you've endured,
From evils which never arrived."
~ Ralph Waldo Emerson
I absolutely love this. It's a great reminder to me that I need only deal with what is right in front of me. Worrying about things that may never happen does nothing to make my life better and, in fact, only increases my stress and anxiety levels.
Focus on the here and now. Concentrate on those things that I can impact and affect. And then get on with the business of living.
