Here's a brief article to remind you about the sole key to consistency--in sports, business, relationships, or anything you do:
Understanding that inner ups and downs are normal.
That's it. The extent to which you grasp that it's normal for thought (energy) to ebb and flow--and that it's normal for your mood to trend with it--will determine how consistently you live up to your God-given potential.
Because excellence is easy when moods trend up. But when moods trend down, those who don't understand are inclined to cope (blame, control, fix). And you cannot cope and contribute to the greater good at the same time.
Keep in mind: The human experience will always be one of inner ups and downs. But your potential to excel never diminishes. Want consistency in your life? Understanding always trumps coping. Besides, coping takes too much time anyway. You've got better things to do. The world's in need.
