How to Make Friends as an Adult (When It Feels Hard)

Figuring out how to make friends as an adult is often harder than it was at school, largely because adult life thins out what used to do the work for you: shared hours, the same faces every day, and free time. That is a change in your circumstances, not a flaw in you.

A 2023 APA feature on the science of friendship, which rounds up social connection research, notes that friendships can be made and maintained at any age. You just have to build the conditions on purpose now.

If the heavier feeling underneath is loneliness itself, how to deal with loneliness and rebuild connection covers that side; this post stays practical.

Why Is It So Hard to Make Friends as an Adult?

A large part of the difficulty is structural. Drawing on earlier work, friendship researcher Jeffrey Hall notes that free time is tight, especially for working adults and parents, so people have to budget their time on purpose to make time for friends.

Using the American Time Use Survey, researchers Viji Kannan and Peter Veazie found that average time spent with friends fell from 60 minutes a day in 2003 to 34 minutes a day in 2019, and to 20 minutes in 2020, a pandemic year. The authors describe work hours as a structural constraint on social time, though a time-use trend is not proof of any single cause. The fall from 2003 to 2019 was steepest for the youngest group, ages 15 to 24, and the data do not say why.

In a 2022 CDC survey of adults in 26 states, 32.1% said they felt socially isolated from others at least sometimes, and the share was highest among 18 to 34 year olds, at 43.3%.

The old default, where friends simply appeared, has faded for many people over the past two decades, which is part of why people call this a loneliness epidemic.

What Is the Proximity, Repetition and Vulnerability Formula?

It is our shorthand for three conditions the sources below keep returning to: being near the same people, seeing them again and again, and a setting where you can open up a little. It is not a tested recipe: the first two parts have research behind them, and the third rests on a clinician’s advice.

Proximity comes first, but it is not enough. In his study of how friendships form, Hall, citing earlier research, notes that proximity and opportunities for contact set the stage for friendship but do not guarantee it. In one of his two studies, time together at work or school was associated with less closeness, while time hanging out was associated with more.

Repetition turns a familiar face into someone you know. In a 2023 interview, Robert Waldinger, who directs the Harvard Study of Adult Development, said that when people repeatedly have casual contact with the same people, “that’s the easiest place to start deepening relationships.” He added that a group built around something you care about gives you something in common, a natural place to start conversations.

Vulnerability is the last step, and it can be small. Hall’s work on everyday talk adds that closeness does not hinge on deep disclosure alone: meaningful conversation, catching up and joking around are linked with more in-the-moment closeness than other everyday talk, including small talk. Psychotherapist Natacha Duke tells Cleveland Clinic that talking about a shared experience, such as a book, opens room for vulnerability. So the small step is one exchange past logistics.

Where Do Adults Make New Friends?

Practitioners and researchers point to places that put the same people together on a regular schedule around a shared interest: a class, a walking or running group, a book club, a volunteer shift, a community garden. In our view, which group you pick matters less than going back to it. Duke notes that app meetups can sometimes be one-offs, though an app can work well if you click with someone.

Where you work matters too. In Gallup’s 2024 workplace data, fully remote employees were more likely to report feeling lonely a lot of the previous day (25%) than those working fully on-site (16%), with hybrid workers in between at 21%. That is an association, not proof of cause, though remote work can mean fewer chances to see the same people daily.

If your social life has mostly moved onto a screen, what social media does to your mental health is worth reading too.

How Long Does It Take to Build a Real Friendship?

Hall’s research estimated that it takes somewhere between 40 and 60 hours together to form a casual friendship in the first six weeks after meeting, and considerably more to become close friends. If a new connection still feels light after a few meetups, that is the normal pace.

Hall found that the chance of moving from casual friend to friend passed 50% after roughly 80 to 100 hours together, and that the chance of becoming good or best friends passed 50% after somewhere between 119 hours over three weeks and 219 hours over three months. These are estimates from self-reported hours in two groups, 355 adults who had recently moved and 112 first-year students.

Hall notes that more time with a friend is unlikely to be a decision one person can make alone. His hours count all the time actually spent in one person’s company, class time included. As noted above, in one study more of it spent hanging out went with more closeness. So, in our reading, a class gives you repeat contact, and the next step is moving the connection somewhere new, such as coffee after class. Hall offers one reading of such a move: agreeing to a new setting is a way of trying out a new kind of relationship.

What Can You Do If You Feel Too Anxious to Try?

Start smaller than feels necessary; it will often go better than your nerves predict. Research reported by the APA found that conversations with strangers tend to be less awkward, more enjoyable and more connecting than people expect, and that talking to strangers can get easier with repeated practice.

Researcher Gillian Sandstrom suggests two openers: ask someone what they are reading, or comment on the shared situation, because “there’s always something in common.”

Duke’s advice is to lower the stakes: skip the hunt for a new best friend and focus on good conversations with good people. Assume you will be liked, because “People like you more than you think they do.” For people with social anxiety, she often recommends volunteering, because it tends to be very structured.

A simple plan, in our words: choose one recurring activity, go at least three times before judging it, and after a few meetings try Duke’s line, “Do you want to grab coffee after class?” If nerves spike in the moment, coping skills for anxiety can help you settle.

InnerSmith is being built for the moments around these small steps, like the jittery ten minutes before a first class. It matches a short calming activity to how your day actually felt. The app is pre-launch, and the waitlist is open.

When Is It Time to Get Help?

Talk to a professional if anxiety about social situations starts causing problems in everyday life, such as avoiding friends, family or situations at work. The National Institute of Mental Health says that is the point to seek help, and suggests starting with a primary care provider, who can refer you to a qualified mental health professional.

Feeling nervous about meeting new people is common and is not a diagnosis; only a clinician can tell whether something more is going on. NIMH notes that cognitive behavioral therapy, a research-supported talk therapy, is commonly used to treat social anxiety disorder. If loneliness ever comes with thoughts of harming yourself, call or text 988 in the US to reach the 988 Suicide and Crisis Lifeline, or contact local emergency services elsewhere.
