__________When you’re a kid, or in high school, or in college, you don’t really work too hard on your friend situation. Towards the bottom of the mountain in the orange zone, you have your Tier 3 friends—your Not Really friends. Rock friendships don’t just make us happy—they’re the thing (along with rock family and romantic relationships) that makes us happy. If you’re in your mid-20s or older, your current rocks are probably the only ones you’ll ever have. Your rock friendships don’t warrant 2x the time you give to your other friends—they warrant 5 or 10x.
