One is made a mason, and doesn't just choose to become one though. The point I think in this thread about a new plan is getting exposure to other men and their roles and find out how you might fit being useful at something else. Masonry is interesting and you meet more new people than you may have in school, but I wouldn't go into it with any expectation other than going on an unexpected journey. Though I also heartily recommend it. It takes some basic courage (or crazy) to approach a lodge, and and that itself is a pretty good filter.
The bar that you have to believe in a supreme being disqualifies a lot of tech people. The people I have seen fail out of it were typically in outside sales, politicians, and other people whose jobs involved transactional relationships with others. The guys who stick around are senior individual contributors, entrepreneurs, trades, pro musicians, corporate lawyers, accountants, military, execs, and a large cohort of private school guys or ones who were in frats at school. For me, I saw the quality of people who have claimed to be against them and decided that was as good a recommendation as any.
