Friends provide encouragement and support during difficult times, helping to build self-esteem and confidence. They can also encourage you to try new activities and experiences outside your comfort zone. The values and behaviors of your friends can influence you, so surrounding yourself with generous, family-oriented and ambitious friends can help develop those qualities in yourself. To nurture friendships, make time for quality conversations, end one-sided relationships, communicate regularly but also in-person, and be generous with praise but cautious with criticism. Loyalty during both good and bad times is essential, and acts of kindness can deepen any friendship.
