Based on what I've seen in real life in the American version of this, you can be pretty "intellectually successfully" just from being pushed, although they lack the "spark"; I can't imagine this producing an entrepreneur (and I'm not just saying that because this is HN; that really is the opposite of where they end up).
The problem is that every other kind of success tends to be elusive, up to and including "succeeding in not committing suicide". (Fortunately, I don't quite know anyone who made it that far, but I know some people who came close.)
