“20% of your relationships are causing 80% of your stress. Eliminate them. Every year, conduct a relationship audit: Which of my friends/family/coworkers/romantic partners consistently cause me to lose my friggin' mind?? If you hang out with 15 people on a regular basis, you'll probably find that roughly 20% (so, 3 people) cause you the vast majority of your stress and frustration. Ditch them. Your life will be better, I promise. And you'll have more time and energy to devote to everybody else.”
