Last night the trainer offered one piece of advice that really hit home on many levels. He suggested that rather than cutting things out of my diet, I try adding things in. Add more vegetables, add more fruit, add more protein. By focusing on what you are adding, rather than subtracting, positive changes will naturally happen and be less stressful.
I think that is good advice generally. Focus on positive additions instead of negative subtractions. Focus on adding good things to your life, more fun, more enjoyment, more pleasure. Think less about what you shouldn't be doing, and more about what you want to do. I think I'll try that out.
