Does this sound like the set of challenges you might be facing?

  • I’m about to walk into a new job and a new neighborhood, and I’m already bracing for it to be awkward, rehearsing how they probably won’t take to me
  • I’ve noticed all my friends come from the same narrow slice of my life
  • I’ve never even properly introduced myself to the neighbor across the hall or the coworker at the next desk
  • On paper I live and work close to plenty of people, yet somehow our paths never actually cross
  • I keep waiting to "meet the right people" but honestly my days are built so I barely cross paths with anyone new the same way twice

Practices that may help

  1. The Propinquity Effect (Leon Festinger)
    The propinquity effect, documented by Leon Festinger's classic apartment studies, is the finding that physical proximity — living near someone, sitting next to them in class, working on the same floor — is one of the strongest predictors of friendship formation. Proximity drives repeated exposure, which builds familiarity, which is interpreted by the brain as safety and liking. The implication is that the architecture of your daily life shapes your friendships far more than active choice does.
  2. Use the anticipation of interaction to create liking before meeting
    Knowing you will interact with someone in the future makes you evaluate them more positively before it happens.

  3. Counteract propinquity bias in friend selection
    Proximity is a powerful friendship filter — but it is not the same as fit.

  4. Invest in the people physically nearest you
    Your immediate neighbors, officemates, and classmates are your highest-ROI friendship investments — propinquity is already working.

  5. Understand functional distance and not just physical distance
    It's not just how far you live from someone — it's how often your paths cross.

  6. Design your daily environment to create repeated exposure
    You cannot become friends with people you never run into — engineer the run-ins.

  7. Become a regular somewhere
    Returning to the same place on a predictable schedule is the simplest propinquity intervention available.

  8. Identify the other things that will also be true of your future life
    Focalism makes future events seem bigger than they are by ignoring all the other things that will still be present.

  9. Show up consistently to build familiarity and trust over time
    Regular, low-key presence across time increases liking without any single memorable moment.

  10. The Habit Discontinuity Effect
    The habit discontinuity effect, studied by Phillippa Lally and Bas Verplanken among others, shows that environmental disruptions — moving house, changing jobs, starting university — weaken the contextual cues that sustain existing habits, creating a window of increased behavior malleability. Evidence comes primarily from observational and survey studies; the effect appears real but its magnitude varies considerably by habit type and individual.
