Worry does not help tomorrow's troubles, but it does ruin today's happiness. Remember, we have choices about our thoughts. We change television channels when we are bored or don't like the program. Imagine a brilliant red sunset. Notice the sun disappearing into the horizon.
Nothing is left except a gorgeous pink sky.
Now switch your mental channel and see a pitch-black sky with a full moon beaming at your. Visualize two cows jumping over the moon. Switch your mental picture again. Now see a red fire engine and ear the sirens blasting. Picture yourself behind the wheel wearing the fire chief's hat.
