"Eton's great strength is that it does encourage interests--however wacky. From stamp collecting to a cheese-and-wine club, mountaineering to juggling, if the will is there than the school will help you. Eton was only ever intolerant of two things: laziness and a lack of enthusiasm. As long as you got "into something," then most other misdemeanors were forgivable. I liked that: it didn't only celebrate the cool and sporty, but encouraged the individual, which, in the game of life, matters much more. Hence Eton helped me to go for the Potential Royal Marines Officer Selection Course, age only sixteen. This was a pretty grueling three-day course of endless runs, marches, mud yomps, assault courses, high-wire confidence tests (I'm good at those!), and leadership tasks. At the end I narrowly passed as one of only three out of twenty-five, with the report saying: "Approved for Officer Selection: Grylls is fit, enthusiastic, but needs to watch out that he isn't too happy-go-lucky." (Fortunately for my future life, I discarded the last part of that advice.) But passing this course gave me great confidence that if I wanted to, after school, I could at least follow my father into the commandos."
