If your journey (pursuit) is leaving you drained and unhappy and unpleasant to be around... something is out of whack. Maybe your goals, maybe your "why", maybe your expectations, or your balance. Or maybe you're just running so hard that you forget that every once in a while your batteries need re-charging.
Take a day off from the pursuit; take an intentional moment to sit and relax, concentrate on and enjoy the parts of your life that are good. Get back in touch with -- appreciate and be grateful for -- the good and positive things, people and circumstances that already exist in your world. Take a day to enjoy your existing happiness... then get back to the pursuit "tomorrow."
It will be a good thing. Trust me.
