"Your relationships should actively contribute to your overall enjoyment of life," Hidary said. "The quality of your life is directly related to the quality of the relationships in your life. You do not have to stay in a relationship that brings you down, undermines you, or holds you back from your personal growth." Take an inventory of the investment you're making in friendships that might not serve you, and be more mindful of that moving forward. "Your time and your energy are precious," Hidary explained. Protect them."
