my advice: find a niche and become the best within that niche. if it's in IT, and you can work for the government, even better.
there's only a handful of people in the UK who can do what I do, and I'm probably at the top of that tree, so I *should* be ok for a while - especially as my job involves cutting operational costs.
I am avoiding being total smugness, however, because any contract is only as good as it's notice period, despite the fact I've just been extended to june 09.
i do feel comfortable enough to piss away $$$ on karting though
