If you are worried about the Labor Day barbeque because you are uncertain if you can make a healthy choice ask yourself if you are using this event to predict failure. Be honest with yourself in an effort to recognize the situations and circumstances where you need to retrain yourself. You should take 100% responsibility for your choices.
This isn’t about expecting yourself to be perfect either. Do not look at any event as a roadblock or a stumbling point. Instead as an opportunity to shift your mindset and relearn new habits. A practice session. After all, habit patterns are things you learned. And if you learned them you can unlearn them.
Think your choices through. Behavior modification works only if you are consistently repeating new behaviors.
