When you're the one experiencing NRE, mindfulness is the only consistently successful strategy we've seen. Be aware that you're not in your right mind, that your perceptions are distorted, and that your judgment is impaired. Don't make life-altering decisions while intoxicated. Don't pledge your life to this marvelous person you met last week. Be aware that you will be predisposed to neglect your existing relationships, and try not to do that. Be willing to do a reality check.
