Most advice about friendship starts with other people. Meet more people. Ask them good questions. Find your tribe. Put yourself out there. Follow up. Make plans. I think it starts one step earlier with this question.

Do I like me?

Not am I perfect? Not have I resolved every insecurity and become a completely self-actualized human being? Nobody would ever make a friend. The question is whether I have gotten my own stuff reasonably straight. Do I have interests? Energy? Can I relax? Something to talk about? Something to contribute? Can I enjoy my own company? Can I tolerate someone not liking me? Am I building a life another person might actually enjoy joining for a few hours?

Friendship can help us enormously, but another person shouldn't have to supply the life we haven't yet built for ourselves.

Get yourself reasonably ready. Then a few more interesting questions unfold.

Your Likability: Do I Enjoy You?

This is the simplest layer, and there is no reason to make it complicated. Do I like being around you? Maybe you're funny. Maybe you're warm. Maybe you're interesting. Maybe you're kind. Maybe we can talk for two hours without noticing the time. Maybe I just feel good when you're around. We can analyze likability endlessly, but eventually the organism gets a vote. Do I enjoy you? If the answer is no, there probably isn't much reason to build a friendship. If the answer is yes, there is something to work with.

Our Chemistry: Do We Activate Each Other?

Likability isn't quite enough. I know plenty of perfectly likable people with whom almost nothing happens. Chemistry between people is different. Something starts moving between us. You say something that makes me think of something great. I make you laugh, which makes me funnier. Your enthusiasm raises mine. We interrupt each other because we both suddenly have something fun to say. Two hours disappear. Neither person is simply performing for the other. We activate each other.

That is why chemistry is hard to predict from a list of attributes. Two terrific people can produce nothing extra together. Two fairly ordinary people can somehow become fascinating and energized in combination. Something happens in the space between them.

Catalysis: Do We Bring More of Us Into Expression?

This is where friendship gets really interesting. Some people bring more of us out. Around them we become funnier, more curious, more adventurous, more thoughtful, more expressive. We tell stories we haven't told in years. We try something we normally wouldn't try. We become unusually engaged with the world around us. There are rare people who seem to do this with almost everyone. People leave them feeling seen, interesting and unusually alive.

That is different from charisma. Charisma makes me think you are fascinating. Catalysis can make me feel more fascinating myself.

And here is the part we often miss when evaluating potential friends: I can be the catalyst too. My curiosity may bring more of you out. My enthusiasm may increase yours. My invitation may put you somewhere you come alive. My choice of activity or group may expose a version of you I never saw sitting across from you at lunch. Before deciding what someone has to offer as a friend, it is worth asking: What am I bringing out in them?

Friend Formation: Do We Turn It Into Something?

Now we have to do something with all this potential. Great chemistry can produce one fantastic evening and then disappear forever. Friendship requires repetition. We have lunch again. Go to another concert. Play golf. Meet each other's friends. Go for a hike. Watch a game. Have dinner. Help with a project. Do absolutely nothing important together several times.

Shared experience begins accumulating. Inside jokes appear. Stories develop. We learn each other's rhythms. Expectations form. Trust grows. We start building history. The relationship moves from I met someone I really like to this is my friend. That transition doesn't happen because we identified enough compatible personality traits. It happens because we repeatedly turned potential into shared experience.

Reciprocity: Do We Both Begin Sustaining It?

Only now do we arrive at one of the most important tests of friendship. Does the other person help sustain it? Do they call sometimes? Invite? Suggest something? Show up? Bring energy? Remember? Contribute? This matters because you can start a friendship by supplying more than half the energy. Somebody often has to. But you cannot sustainably maintain a friendship by supplying nearly all of it forever.

That doesn't mean keeping score after every lunch. People have difficult months. One person may naturally organize more. Contributions can take very different forms. But over time there should be a feeling that we are both in this. Friend formation can begin asymmetrically. Friendship cannot remain permanently one-sided.

So What Actually Makes a Friendship?

Put it together and a surprisingly complete picture appears.

Self-readiness → Do I like me? Have I gotten me reasonably straight?
Likability → Do I enjoy you?
Chemistry → Do we activate each other?
Catalysis → Do you bring more of me into expression?
Friend formation → Do we repeatedly turn that activation into shared experience?
Reciprocity → Do we both begin sustaining it?

Real friendship won't always proceed neatly through these stages. Friendship isn't an assembly line. Chemistry can appear instantly. Reciprocity can begin on day one. Someone can bring out a wonderful part of you before you've even decided whether you like them. This isn't a checklist. It is a way of seeing what has to happen somewhere along the way.

And notice where the judgment comes. Not first. First I work on myself. Then I notice you. Then we discover what happens between us. Then I ask what more we can bring out in each other. Then we invest enough to build some history. Only after we've given friendship a reasonable opportunity to exist does sustained reciprocity become the test.

That changes the posture of making friends. Instead of standing outside the relationship asking “Are you good enough to be my friend?”, I have to step inside it and ask: “What can we make here, and what am I doing to help make it?”

That is a much harder question.

It is also a much more hopeful one.
