It takes multiple touchpoints with something before people get interested in new ideas, or take them seriously.

For instance, take how I got into with the Carnivore diet. I certainly thought it was extremely weird at first. Then after getting into bitcoin, I realized that carnivore was a big thing with bitcoiners. Then I found out Saifadean Ammous (author of The Bitcoin Standard) was a carnivore. I listened to some interviews with people on his podcast, read the books, and was converted.

So - multiple, incremental touchpoints.

This was your hairdresser's first touchpoint.
