Research suggests that we replace half of our friends every seven years, continually pruning and making new friendships throughout life. It's important to recognize that people change and not expect others to remain the same. While some friendships may evolve, it's not always feasible to maintain connections with everyone. Create space for new friendships without fear of not finding anyone. Don't believe that you already have all the friends you need, as opening up to new people can have a profound impact. Say yes to invitations and activities, and don't limit yourself to one type of person or rely solely on the length of friendship for closeness. Don't think you're past your friendship prime or react with fear when relationships change. Foster deep love and belonging, even if a relationship has shifted. View friendships in levels, and keep the door open for friends who may be in a different stage. Let them promote themselves back up.
