You aren't battling your ability to stick to a diet, execute a business plan, repair a broken marriage and rebuild your life, hit your goals, or win over a bad manager- you are battling your feelings about doing it. You are more than capable of doing the work to change anything for the better, despite how you feel. Feelings are merely suggestions, ones you can ignore. To change you must do the same, you must ignore how you feel, and just do it anyway.
