If you are a runner, be thankful for every obstacle, every burning breath, every hill you think will never end. They make you stronger.
If you are a writer, appreciate every slight, every trial, every moment you spend with your face in the dirt. They make the best stories.
If you are a ranter, consider running or writing. You’ll never run out of material, and in the midst of your misery you’ll be happier than you’ve ever been in your life.
