I'm not shocked by the figures. The thing that all should remember is that every hurdle you leap over on your way to that dream job (whether it's a pilot, lion tamer or whatever), your odds of success are increasing massively. Many will fall before the first fence.
Its those that stick at it due to planning, determination and just a little luck that make it. Don't just dream, do it. But for god's sake, go in with your eyes open!
