In terms of ambition, Boothroyd possibly stayed at Watford for too long. The writing was on the wall when financial problems emerged. You cannot fault his commitment in wanting to take Watford forward though.
He'll have to get back into football somehow as the Premier-ship job has sailed (he was long touted as a possible big-time manager once upon a time) - but he'll wait and see what comes up. For example a job like Sheffield Wednesday would be a good gig for him. If he's in Australia observing (the Aussie Institute of Sport I would guess!!) then he'll be out for a while.
Bascially, I'm saying that he could still wait and get a Championship job.
If you're around the management game at the top end for a while, then you can set yourself up by being sacked and living off the pay outs....someone like Dowie, must have trousered a small fortune in the last few years, from signing decent contracts and being sacked a few months later.
Boothroyd having got Watford up, and having had some Prem experience, probably would be on at least a quarter mill pa.
I saw an interview with Cotterill a while back where he was asked about his future career and he said he was waiting for at least a Championship club. He probably got a decent pay out from Sunderland and Stoke.
Compare this to the Sturrock attitude, I'm a manager...I need to work....believe in taking the first decent offer that comes along.
