There’s no denying it — friendships make life better. Yet, Americans suffer from a loneliness epidemic. Our culture seems to rely solely on a spouse to fill our friendship tank, but that’s asking too much of one person. Have friendships become watered down, overlooked, underutilized and generally misunderstood? I think so. In my new book, I’ll reveal what friendships reveal about you, and what you can do about it.  

Book cover titled 'The Friendship Zones' by Lester Lin with abstract geometric shapes and a subtitle that reads 'redefining friendships that go beyond marriage'.

What’s the Book About?

When is a friend actually a true friend? Can a spouse be your “best friend?” What do friendships reveal about yourself? Based on my own experiences, interviews and research, I’ve come to believe that Americans have overlooked the power of friendships. And, I think that’s a mistake. Here’s what my book is about:

The Quiet Crisis Behind Connection

Americans are in a friendship recession and loneliness epidemic, partly because we’ve been raised to believe marriage is the ideal goal. But what if the marriage fails, or if you choose to be single? 

Friendships Make Life Better

Research verifies people with close friends live longer, heal faster, and report more joy in daily life. Friendships buffer against depression, anxiety, and grief. They expand our sense of meaning.

Friendships Come in Different Shapes and Sizes

I call them “zones,” because an acquaintance is different than a companion, and a companion is different than a close friend. And a close friend is still different than a “covenant” friend. Yet, every covenant friend starts as an acquaintance.  

What is a Covenant Friendship?

I introduce this term to explain a relationship that’s as close to a marriage as possible. It is the highest zone and most closely held and protected of all friendships. If you’re lucky, you’ll have one of these someday.
