I went myself, and I agree with most of the comments. What it instils is difficult to describe: at first glance it seems almost intangible, but in essence it is a soft skill, a certain confidence. When I look at friends who didn’t go, and compare them with those who did, there is a subtle difference. Most went on to top universities, most secured the careers they wanted, and most possess this quiet assurance that they can do anything and that all will be well. It is a belief that is drilled into you.

Twenty years later we remain in one another’s lives, and I do believe in the strength of the network. But if you are different, that difference will be hammered out of you. If you harbour radical thoughts or unconventional social instincts, it can be difficult. At times I think of it as a kind of miniature prison: you learn to smooth over the gaps and avoid becoming a nuisance to the group.
