You won't stress over it unless you care.

We are semipermeable membranes. We can pick and choose which troubles are worthy of our attention. What sinks us can only do so with our permission; a boat stays afloat until the water gets in.

It's because the door hasn't been closed yet that the nightmares still find their way in.

Be thankful when you find yourself worrying about the smallest things, for it often means there aren't any bigger things to truly worry about.
