Er, yes and no in my case.
I don't have the confidence to go it alone in what I do. The knowledge that my wages pay the mortgage, bills, cars etc makes me more nervous.
Simon however is pee'd off in his job, (there's not much opportunity to use your noggin) and he'd be brilliant if he had his own business. We're looking into a couple of ideas including buying a 2nd hand Rolls and doing weddings/events or buying into a franchise.
Start small and build up!
How's that for a convuluted answer...well, you didn't expect me just to say yes or no did you?!
Good luck Ian, difficult decision to make!
