Stumbled upon your response to how do I learn to play bridge? And I so approve of the response! Best way is to (at least first year) learn from friends. I'm an old lady who's played sociable bridge since the 50s. Back then everybody just learned from friends -- dragooned by a threesome (my husband and our best friend couple) to learn to play so we could have a foursome. I truly believe that formal (especially ACBL) lessons turn people off on bridge.
It is my end-of-life cause to have the boomer generation take up bridge as their parents did in the 50s. But if the usual advice is followed -- call the ACBL and take some lessons -- most will be turned off before they ever discover the delights of playing sociable bridge.
I would be happy to post the last chapter of my book "Bridge Table or What's Trump Anyway?" on the history of bridge from the ladies-only bridge-lunch club viewpoint. In it, I say, if you want to learn to play bridge, don't take formal bridge lessons to begin with. Once you play a while (badly even) you'll know if you have the DNA of a competitive player. Then take bridge lessons.
The thing is -- and it is one of the premises of my book -- the era when bridge was a major fad (30s and 40s) and a pop culture icon (50s and 60s) was made so by the sociable players who have always vastly outnumbered the serious players who don't speak and are intimidating.
At 90, I can tell you boomers out there: one of the best things you can do to live to 90, dementia-free, is learn to play bridge. In your advice you don't mention one way I find very appealing. Get a book that offers playing cards with coded backs, so that you can deal the hand the lesson is about and do it over and over by yourself until you "get" it.
