Become genuinely interested in other people

You make more friends in two months by being interested in others than in two years trying to make them interested in you.

Why it works

Attention is a scarce, valued resource, and people reciprocate the regard they receive. When your curiosity is real rather than performed, the other person relaxes their guard and mirrors your warmth — a liking loop that compounds. The word "genuine" is doing the work: simulated interest reads as manipulation and triggers the opposite response.

How to do it

1. Before a conversation, set one goal: leave knowing something you didn’t about them.
2. Ask about what they care about, then ask a follow-up about their answer rather than pivoting to yourself.
3. Notice and remember a detail to bring up next time — proof the interest was real.

Evidence

Carnegie offers anecdote, but the underlying liking-reciprocity dynamic is well documented in social psychology: we tend to like those who show interest in and warmth toward us. Experiments confirm that asking questions — a direct expression of interest — measurably increases how much a partner likes you. (anecdotal)

The principle is practitioner advice; the reciprocity-of-liking effect it leans on is the researched part. Interest faked as a tactic tends to backfire.

Common mistake

Performing interest as a technique — nodding while waiting for your turn to talk — which people detect as instrumental and resent.
